Targeted drug delivery using red-blood cells for transport
Platform technology for targeted drug delivery using red blood cells for transport. Problem: Drug delivery can often result in up to 99% of the drug being delivered to off-target organs. This can lead to side-effects and toxicities. Current methods that bind drugs to red-blood cells for transport can require modifying the structure of the red...

Nanoparticle catalysts for high performance methane combustion
Problem: Methane, also known as natural gas, is a widely used in power generation and has the advantage of producing lower carbon emissions than coal per unit of energy generated. However, the release of any unburned methane during combustion presents a problem, as methane is a potent greenhouse gas with a heat-trapping effect 20 times greater than...

Nanowire phase change memory
Problem: Phase Change Memory (PCM) is a leading contender to replace flash memory. In PCM devices, a material is heated to undergo glass transition, changing back and forth between the amorphous and crystalline state. However, existing PCM devices have experienced problems with reliability and threshold voltage drift. In order to make commercially...

Diamond Waveguides for Photonic Devices
Problem: Photonic Integrated Circuits (PICs) can transmit information for computing using light rather than electricity. Using PICs on chips would allow for faster data transmission rates, lower power consumption, and less energy wasted through thermal dissipation. Diamond is a promising material for PICs due to its optical properties, however, fabrication...

Robust Smart Windows: Reversible Switching from Transparent to Color
Technology Overview: A composite film consisting of a thin layer of quasi-amorphous array of silica nanoparticles (NPs) is embedded in a bulk elastomeric polymer film. It is highly transparent (>90% transmittance in the visible wavelength) in the initial state. Upon mechanical stretching, the transmittance is dramatically reduced to 30% and...
