Two-Photon Laser Triggers Nanoparticles to Release Chemotherapy Drugs Directly in Tumor Cells

Researchers from UCLA's Jonsson Comprehensive Cancer Center have developed an innovative cancer-fighting technique in which custom-designed nanoparticles carry chemotherapy drugs directly to tumor cells and release their cargo when triggered by a two-photon laser in the infrared red wavelength.

Phonon Spectrometer Precisely Measures Subtle Movement of Heat in Nanostructures

How heat flows at the nanoscale can be very different than at larger scales. Understanding how surfaces affect the transport of the fundamental units of heat, called phonons, could impact everything from thermoelectric materials to microelectronic cooling devices.

Researchers Advance THz Spectroscopy for Detection of Explosives from Greater Distances

Standing in a full-body scanner at an airport isn't fun, and the process adds time and stress to a journey. It also raises privacy concerns. Researchers now report in ACS' The Journal of Physical Chemistry Letters a more precise and direct method for using that "terahertz" (THz) technology to detect explosives from greater distances.

New Optical Circuit with Bendable, Stretchable Optical Interconnections

For futuristic applications like wearable body sensors and robotic skin, researchers need to ferry information along flexible routes. Electronics that bend and stretch have become possible in recent years, but similar work in the field of optics – communicating with light instead of electrons – has lagged behind.

Researchers Present Nano Scale Disruptive Silicon-Plasmonic Platform for Chip-to-Chip Interconnection

Thanks to optical signals, mails and data can be transmitted rapidly around the globe. But also exchange of digital information between electronic chips may be accelerated and energy efficiency might be increased by using optical signals. However, this would require simple methods to switch from electrical to optical signals.
