Craig: tractor beam technology.

Jon: yeah. this is pretty complex stuff that we're gonna get into, just a heads up. it took me a little bit to wrap my head around this. but, so this is, again, out of mit, which they're always coming up with crazy stuff, but, we're talking star trek based not star trek based, but, we're talking tractor beam technology that you may have heard of in star trek, star wars, all those different things. but they've developed a groundbreaking chip based tractor beam. so it can manipulate biological particles using light. so, again, it's it's really small. it it can fit in the palm of your hand, and it uses a tightly focused beam of light that's emitted from silicon photonics chip to capture and move cells and other microscopic objects millimeters away from the chip surface, which is crazy, really cool. so it's like, it's it's it's definitely an advancement over traditional optical tweezers because those typically require bulky microscope setups, but we don't have to get into that now. but the cool thing about this, the way that it works, is it uses what's called an integrated optical phased array, to generate and control the light beam. so what they've done is by creating specific phase patterns for each microscale antenna on the chip, they were able to achieve an intensely focused beam, which traps particles over a much greater distance than the previous chip based optical tweezers, which allows them to manipulate cells while remaining in a sterile environment. so what are your thoughts on this, craig? i'm curious to know because i do a lot of talking here.

Craig: this is one of those things that are really cool, but it's early stages. like, it allows precise control of cells through glass, maintaining sterility and avoiding contamination. so you can really, you know, manipulate cells under the skin and stuff. so, like, it's not star trek. let's grab a ship out of, the thing and stop it from moving away, but it is coming close to telekinesis.

Jon: it is. yeah. because, you're you're gonna have like you said, the ability to manipulate cells and other biological particles without direct contact.

Craig: so yeah. the beam manipulates particles millimeters away from the chip surface. the device uses silk you mentioned all that.

Jon: yeah. it could be used in diagnostic tools for more efficient cell sorting and analysis. it could be used in minimally invasive procedures allowing for manipulation of cells or even drug delivery vehicles within the body. i know, the other one we were talking about, the anthrobots, those could also be used for drug delivery as well. but, but yeah. so there's a lot of different implications, for this technology. but, again, we cover things that are so new, like, that, yeah, there's so much more to be discovered. right?

Craig: yeah. i mean, like, right now, the device is small enough to fit the palm of your hand. the device enables optical trapping and tweezing without a complicate, complicated bulk optical setup. like, i would imagine that if it was cheap enough, people will start using this for tweezers. never mind, you know, because once you start, you know, you don't necessarily have to be at invasive and whatnot. but this, like, it's it's really cool. we're on leading edge. like i said, if they can fit this in the palm of your hand now, what's it gonna be like in ten years?

Jon: exactly. yep.

Craig: you know, if we're moving, these things, millimeters, thickness. so now we can normal, typical sterile glass cover slips are about a hundred and fifty microns thick, so this thing will penetrate that. so now you can manipulate stuff inside the glass, inside the test tube. this is great for studying dna, classifying cells, and investigating disease mechanisms without, you know, possible ability of infection or, whatnot. it's amazing where we've come from. like, i like where this is, and i would extrapolate farther that it wouldn't be long, i believe, that we would be able to manipulate things that are much farther away.

Jon: yes. yeah. they just have to work on the antenna technology and the chip technology. right?

Craig: absolutely. and, you know, when you can use light to manipulate things, you start to wonder about, the physicality of light. yes. so i just didn't know if it could

Jon: be built. brings up so many other questions, so many other, like, like, things that we haven't even thought of. right? and, yeah, it's it's crazy. it's scary, but it's interesting.

Craig: absolutely. and, you know, we don't think about the physicality of light because, you know, it's just there. it doesn't hit us. but, you know, we can feel it. we can see it, but we you know? but then now you can use light to manipulate objects and physically move them. you're like, well, that becomes different. our perception changes on all of these things. but yeah. you know, i guess laser is light too. right? so, it can really do damage and do other things. we'd really like to know what you think where this is going. tractor beam technology, are we gonna see telekinesis, tools? are we gonna see other very cool, interesting tractor beam technology tools in the future? let us know.
