00:04 Welcome back to The Creator Revealed.
00:06 Today we're talking about Molecular Machines,
00:10 the little machines in molecules.
00:12 And who better than a nanochemist
00:17 to have on the second half of the program.
00:19 Exactly, Dr. Ryan Hayes teaches chemistry
00:22 at Andrews University.
00:24 He is a nanochemist, that means a chemist who makes
00:29 really tiny, tiny, tiny little things.
00:32 Now, we've been talking about nano machines really,
00:37 when we're talking about those machines,
00:39 those molecular machines inside the cells.
00:44 So let's meet Dr. Hayes.
00:46 Let's ask him a little bit
00:47 about what exactly a nanochemist does,
00:50 and then we can get into some nano machines stuff, yeah.
00:56 Hi, Dr. Hayes. Thanks a lot.
00:57 Welcome.
00:59 Thank you, thanks for having me
01:00 on this program.
01:02 This is exciting.
01:03 Now, we got to be careful about the term nanochemist
01:06 'cause some people might think that this means,
01:07 I'm a really, really small chemist
01:11 and that's not the case.
01:12 I've met you, you're completely life size, yes.
01:15 That's right.
01:17 But I do study and we actually have a company
01:21 that I'm a part of, where we make nano materials.
01:27 And so to a chemist actually, nano materials are quite large
01:31 but to our eye and to everyone else,
01:33 nano materials are very, very small,
01:37 so small that you can't see them.
01:40 But they are a collection of atoms and molecules to form
01:45 large chemical structures to us.
01:48 But they're usually precisely engineered and controlled
01:54 to give you the right size and functionality
01:57 to do really interesting things.
02:00 And a nanoscientist, nanochemist,
02:03 there's some out there trying to build little nano cars
02:05 and nano sized batteries.
02:08 And I like to build nano sized versions
02:12 of this little suction ball cup,
02:14 can say more about that
02:16 as a little shout out to my students,
02:18 you know, I like to talk about nano materials
02:20 that look like this.
02:21 And, but inside our body,
02:24 there's just an amazing amount of nano sized structures
02:28 doing amazing things there.
02:30 So maybe you can tell us...
02:32 Yeah, maybe you can tell us a little bit about
02:34 what precisely it takes to make these really small structures.
02:39 First of all, are they something
02:40 that you can see under a microscope
02:42 or how would you...
02:44 Are they smaller than that even?
02:49 Well, they're definitely smaller
02:51 than what you can see with the microscope,
02:53 people have been able to...
02:54 Scientists, many of them visualize them
02:56 with things like an electron microscope
02:59 or atomic force microscope.
03:01 And so we have ways of actually getting visualization of them,
03:06 getting their structures, but to build them,
03:09 boy, this is a real tough job.
03:12 And it takes a lot of knowledge of chemistry
03:14 and the rules of how chemicals react with each other
03:18 to overcome thermodynamics.
03:21 These things wanna just spread out,
03:23 but we want to bring all the molecules together.
03:25 So there's some organization
03:28 that needs to be thought of in advance
03:31 to bring these things together.
03:33 So I do this on a daily basis.
03:36 So what you're saying then is,
03:38 there has to be a plan when you start,
03:41 you can't just sort of walk into a lab and say,
03:45 "Let's see what happens when I mixed together
03:47 these chemicals today?"
03:50 That's exactly right.
03:52 Now, my students
03:53 would hope it would be like that.
03:54 Let's just make some things together
03:56 and hopefully get some great nanostructures
03:59 but, no, we have to go in with a plan and a recipe.
04:03 And even with that, even with our best recipes,
04:06 we still struggle to make pure products
04:10 with the desired purpose that we have in mind.
04:13 So yeah, definitely need a plan,
04:16 a good recipe and a good laboratory space,
04:20 that's usually needs to be clean,
04:24 you need to be able to run your reactions
04:27 without interference,
04:28 and all at the right time and temperatures.
04:31 There's a lot of factors that we think about
04:33 to get to the right structures that we're trying to build.
04:36 And we're trying to build, we build some really simple
04:38 nanostructures here,
04:40 especially, compared to what we see
04:42 in living creatures.
04:44 Well, let me ask you about that.
04:46 I mean, you're a smart guy
04:51 and you have all of this equipment,
04:56 if you set out
04:57 to make one of these little nanostructures,
05:00 this relatively simple little nanostructures,
05:03 about how long would it take you to make one?
05:05 Is this something that you can have a good idea
05:08 in the morning and have by the afternoon
05:10 or is it something that takes considerably longer than that?
05:17 That's a great question.
05:19 And it depends on,
05:20 how elaborate you want your structure.
05:22 Now, the ones that we make, they can take weeks and months
05:29 to make the structures that we're looking for.
05:32 And these are relatively simple ones
05:35 that have a lot of repetitive structures to them.
05:39 Yeah, in fact, that's kind of a problem
05:41 is how long it can take and that drives up the cost,
05:46 and these things can be kind of expensive,
05:48 And so, yeah, it can take weeks and months.
05:52 And that's not just letting them sit in a pot
05:54 and stir like a pot of spaghetti.
05:56 We actually have to go in,
05:58 it will do that part for little bit,
06:00 then we have to pull out the materials, clean them up,
06:03 and maybe do some purification,
06:06 and then get them ready for another step.
06:09 We spend a lot of time doing that.
06:10 There is some shortcuts you can take,
06:12 but then you lose out on the structure.
06:15 You won't get the beautiful structures,
06:17 if you try to take some shortcuts.
06:20 It's quite a challenging time, takes quite time.
06:22 And what you're saying, doctor,
06:24 is that this takes intelligent design in a plan
06:30 that has to be carried forward.
06:34 Oh, absolutely.
06:35 And even with simple,
06:37 if there's such a thing as simple nanostructures,
06:40 you definitely need a plan.
06:43 You need an extreme amount of knowledge
06:46 about how these molecules, these chemicals, the atoms,
06:50 the electrons, how all of these things work?
06:54 And without a plan, you're gonna get a mess.
06:57 And as one of my advisors said,
06:59 you put garbage in, you get garbage out.
07:01 We need really clean materials, and you need a good plan,
07:05 you need awesome intelligence to think about
07:08 all of the side reactions that can happen,
07:11 and all the ways to go wrong,
07:12 so that you can prevent those from happening,
07:15 as much as we would like chemistry to just happen.
07:19 Being in the lab is proven to me
07:21 that this is quite a challenge
07:22 to make even simple nanostructures.
07:26 So what do you think about Darwin's theory
07:28 of the warm pool
07:31 and the chemicals coming together
07:32 for this little amoeba like structure?
07:37 Yeah, that's a great question.
07:39 It's important to know the history right there
07:40 and I won't go all into that
07:42 but much of Darwin's thoughts were formulated
07:45 well before chemistry was even established
07:48 in the way that it is in the modern scientific way,
07:50 that we know how chemicals reacting.
07:52 He thought there was just,
07:54 you know, a couple, four or five chemicals
07:56 that came together in a little bubble to make life
07:58 and we know now it's thousands of chemicals
08:01 coming together in a complex not bubble,
08:04 but a surrounding
08:06 and an amazing amount of nanostructures
08:09 that have come together.
08:10 Not just one nanostructure, but many of them
08:13 that have come together
08:15 to form a working living system.
08:18 So warm little pond, I think we would love it,
08:21 if it was that easy.
08:23 But the more we know about life in the nanostructures,
08:25 in the nano materials that life is made out of,
08:28 we understand the complexity that's there.
08:31 And I think, there is a desire or you know,
08:34 that scientists think, well, maybe we're missing something.
08:37 There's some theory that's going to come along
08:39 and change all of this.
08:40 Well, the more we look, the more complicated it gets.
08:43 So this problems not getting any easier.
08:45 So it's getting worse and not better.
08:47 Let me ask you this.
08:50 If you think about these nano machines,
08:53 these complex nano machines
08:54 that we find inside living things.
08:57 If...
08:59 I mean, you're making
09:00 relatively simple
09:01 nano chemicals,
09:07 would there be any realistic expectation
09:10 that we would even have the technology
09:12 to make something like these kinds of complex machines
09:18 that we find inside cells?
09:20 Or what would that really take?
09:24 Well, doing it from scratch,
09:28 I'd say that we're decades and decades away from that,
09:32 perhaps centuries from figuring that out,
09:34 maybe not, but it's a long time.
09:38 You know, what a lot of scientists do now,
09:40 is we just copy.
09:41 We just copy what we see in the cell.
09:44 We take things out
09:46 and we try to change them a little bit,
09:48 to give them some new functionality.
09:50 But all we're doing is modifying the master plan
09:53 that's already been enacted there.
09:55 So people are finding it easier just to mimic,
09:59 what we see in life rather than trying this over.
10:02 So basically, we were plagiarizing.
10:07 Absolutely.
10:08 It's so much easier to just use what's there
10:11 and tweak it for some of our own designs,
10:14 that's there.
10:16 And...
10:18 I'm sorry, we're just running out of time.
10:19 But it's fair to say that you absolutely believe
10:23 that God is our Creator.
10:28 Absolutely.
10:30 I can see it the handiwork,
10:33 when I see the chemicals coming together...
10:36 When we look at a house, we don't go, wow,
10:39 those pieces of wood and nails just blew together
10:41 with the right temperature and wind speeds.
10:44 So there's no question
10:45 when we look at a house that someone built it.
10:47 But when we look at molecules, we say, "Oh!
10:49 I have no idea how that happened."
10:51 So chance can do that.
10:53 But when we understand the chemistry,
10:55 and the mechanisms there,
10:57 we start to see the hand of a designer.
11:00 I absolutely believe that God is the designer
11:03 and the head chemist that put all of this together,
11:05 so that we can have life and have life abundantly.
11:09 Well, thank you so much for joining us, Dr. Hayes,
11:11 that's been a real pleasure.
11:13 And there've been some pretty deep insights there.
11:15 Yes. Amen.
11:16 And it's just exciting to think about that.
11:19 Yeah, I cannot imagine that this particular point,
11:24 how you could put a living thing together
11:26 from scratch,
11:28 even if you did have,
11:29 all of those parts that are necessary.
11:33 It's truly a triumph of a kind of technology
11:40 that we certainly haven't mastered.
11:42 And it's certainly points towards
11:43 an incredible brilliance that's there.
11:45 And when you think about it, I've heard this example before.
11:48 If you have a junkyard and you throw a bomb out there,
11:52 you don't end up with a shuttle.
11:54 And that's what many scientists to support Darwin's theory
11:59 seem to be trying to tell us.
12:00 Well, we hope that you've been encouraged
12:03 to understand that God created you
12:06 and He loves you.
