Molecular Machines: Materials
Switchable molecular tweezers: Guillaume Vives, Institut Parisien de Chimie Moleculaire
- Optical, magnetic, redox, or catalytic triggers can be used to alter molecular structure
- Molecular machines include catenanes, nanocars, turnstille, motors, walkers, shuttles, and muscles
- Molecular tweezers switch between open and closed states using allosteric effects
- Metal coordination is used for the switching unit, while luminescence/magnetism/catalysis is used for the functional arms
- Molecular tweezers have been developed using optical, magnetic, redox, and catalytic triggers
- Guillaume is interested in controlling gels using these molecular tweezers
How can we make the work done by molecular machines on the nanoscale be useful on the macroscale? In materials? : Tom Schroeder, Harvard University
- Crystal propagation can translate work on the nanoscale to macroscale
- Dual lattice structures create interesting mechanical properties
- Nanoscale interactions govern crystal growth in living organisms, such as sea urchin spines and antifreeze proteins
- Tom works with exothermic crystalline growth and uses photomasking to create custom crystal formations
Visible Light DLP Chemical Micropatterning : Uroob Haris, Southern Methodist University
- Developed a method to do microscopic patterning of light to trigger light-enabled chemistry
- 500 nm precision
- Thiol-ene photoclick chemistry and Diazoketone wolff rearrangement are used
- Can pattern chemical processes on single cells
- Microscopic 3D printing
- Applications in the future could include self-propelled micromotors, volumetric 3d printing, drug loaded microcapsules, and high resolution lithography
