A prototype spectrometer made using Georgia Tech’s new technology. This spectrometer can be plugged into a lap top and used for environmental sensing.
New technology allows for more versatile portable spectrometers
Being the delicate optical instruments that they are, spectrometers are pretty picky about light.
But Georgia Tech researchers have developed a technology to help spectrometers — instruments that can be used as the main parts of sensors that can detect substances present in even ultra-small concentrations — analyze substances using fewer parts in a wider variety of environments, regardless of lighting. The technology can improve the portability while reducing the size, complexity, and cost of many sensing and diagnostics systems that use spectrometers. The technology has appeared in Applied Optics, Optics Express and Optics Letters and was presented as an invited talk at the IEEE Lasers and Electro-Optics Society Annual Meeting 2005.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
