Optogenetic Immunomodulation Reduces Cancer Tumor Size, Metastasis in Animal Model
Optogenetics has been modified for an immunotherapeutic approach that aims to kill cancerous tumor cells. Neuroscientists have used light to stimulate neurons for years, said professor Yubin Zhou of Texas A&M University’s Health Science Center Institute of Biosciences & Technology. In neuroscience, optogenetics involves genetically engineering cells to produce proteins from light-sensitive microbes. The result is nerve cells that either send or stop sending nerve impulses when exposed to a particular wavelength of light.

Plasmonic Interferometry Could Enable Compact Bio-, Environmental Sensors
A nanoscale plasmonic interferometry system that eliminates the need for an external coherent light source could enable accurate and compact bio- and environmental sensors. In the device, fluorescent light-emitting atoms were integrated directly within a tiny hole in the center of an interferometer. An external light source was still necessary to excite the internal emitters, but it didn’t have to be a specialized coherent source. The system was developed in the lab of professor Domenico Pacifici at Brown University’s School of Engineering.

FS Lasers Explored for Presbyopia Treatment
A femtosecond laser-based method for treating presbyopia — farsightedness caused by by loss of elasticity of the lens of the eye — could eventually eliminate a patient's need for reading glasses. A virtual model of the technique — called femtosecond- or fs-lentotomy — is being developed to simulate the surgery, in which the eye’s crystalline lens is made flexible again by performing microcuts with an fs laser.

UTA Engineer Alice Sun Tapped for $500K NSF Grant
The National Science Foundation (NSF) has awarded a University of Texas at Arlington electrical engineer with a five-year, $500,000 grant to develop an optofluidic laser for better disease detection. Assistant professor Yuze “Alice” Sun will use her Career Award to create a new-generation laser that will lead to a versatile biosensing platform featuring high detection sensitivity, selectivity and throughput.

Nanoscale Device Adapts Filtering Properties When Stretched
A stretchable nanoscale device that can filter specific colors while remaining transparent may one day be used in smart contact lenses to filter harmful optical radiation, transmit data and gather information. The device was developed by University of Adelaide researchers with expertise in the interaction of light with artificial materials working with researchers in materials science and nanofabrication at RMIT University.
