Get students purchasing jason hafner. Who's of physics and astronomy at rice university. His lab studies nano photonics at inter facial biology. Thanks for your much. Yeah thanks for doing this. So before we get into your your papers I want to send the context of these two things so natto photonics and into fish biology. What do those things need. Yeah sure so Netanyahu has just sort of a part of nanna science in general. You know nanno has been a big thing since Sort of the nineties. This idea that if we shrink material matter or control materials down to the nanometer scale they with the world differently and that's sort of big picture we study so as you can imagine nature. Photonics is doing that with light so normally we think of light does not being real nanno. The wavelength of light is about five hundred. Nanometers is why we have like a limit to what we can see an optical microscope but as delight interacts with materials the nanometer scale some materials will focus the light downed meter skill. Or you know Heat the liar heat up due to the light in special ways so really big picture photonics is just. How can we manipulate the nanometer scale with nettle materials. Yoke okay. we'll get into the details of that deficit deficit have any sort of computational. Applications also computational. Yeah yeah You know Doesn't doesn't have a sense of design or anything like that. The debt are right. Yoga ways to go also competition alexa. We use many competition tools in. It's actually critical in many areas of research these days but especially these interactions. In terms of an application. There are ideas. There are some aspects of y light would be better than electrons chips I mean it's not it's still definitely sort of a research phase stage thing you know. How do you do the couplings. And and in my field we can send light. We can turn the light into an electronic exultation in send it down a metal wire. Have it come out the other end of light which is really cool. But it's very easy. You know metals you'll lose a lot of of the energy so it's definitely been looked at but for now you know i don't think in terms of completely taking over a chip that's still quite a ways away. Yeah i was just thinking you know One of the houston saugus needed. Quantum tunneling issues conventions into this issue all flood heat on chip so i was just wondering if there's a direction there what is interface your biology so really there as a general way to talk about membranes. So if you think about the picture of a cell that you saw whenever the last time you took biology was you know. It had this outer circle the membrane and then inside of these organs and that picture kind of cells membrane short because really remembrance around every one of those organizations you know the the the cells full of membranes on these inter facial membranes lots of the action ought to the biological Action happens so membranes. Very huge Part of sort of microbiology and so biology but also the hardest to study which we can get into later when we talk about What we're doing with it so really. It just means you know where the liquid meets another liquid. The liquid meets the solid. If you want to think of membrane a solid that's inter- facial part each and so this has applications in So you mentioned send biology so it would getting getting into the cell at using the cell infrastructure to replicate itself Do some applications and debt collection. Yes for sure. So that's that's getting sort of into synthetic biology hijacking. That's getting it all biotechnology. Really sort of if you out sort of worked on sensors a lot and i've always it's always interesting realization to me that the most powerful syncing technologies. We have our from hijacking. Biology essays were great in the critical part is the antibodies. We get from an animal and You know. pcr thing amplifies. Dna completely hijacked biology. So yeah so. I forgot what talking about allergies that idea taken that even further membranes are just one component of all that i would say hello. They need to understand memory. It's make a lot of that work but a lot of biology. You can hijack without really understand exactly what's going on. So if we don't understand membranes they'll still be a components of of that kind of technology. There is one area that is membrane home by a membrane specific. And that is you take the cells membrane and you lay flat on a surface and then integrated into sort of a chip kind of technology as kind of a wet chip so these are called or lipid membranes and the ideas you can take some of the ion channels and things from a cell and then turn them into centers on a chip and that also it's kind of like the photonics photonics thing. It's it's it's in progress. It's not happening any day now. But it's definitely a thing idea. That's that's coming along. And so i want to have the budget order papers Entitled a two hundred dollars plasmon residents
