Abstract: Disclosed is a method for body fluid-based neurodegenerative disease diagnosis through high-sensitive immunoassay of aggregated proteins by photooxidation-induced amplification. The method according to the present disclosure provides an effect of quantitatively analyzing aggregated proteins in the form of oligomers or monomers which are present in trace amounts in a body fluid and measures normal or abnormal protein aggregation by detecting the aggregated proteins in the form of oligomers or monomers with high sensitivity by reaction of antibody-conjugated enzymes selectively bound to the aggregated proteins with substrates and photooxidation-induced amplification, thereby allowing accurate diagnosis of a neurodegenerative disease.

Abstract: Alloys of GeSbSeTe (GSST) can be used to make actively tunable infrared transmission filters that are small, fast, and solid-state. These filters can be used for hyperspectral imaging, 3D LIDAR, portable bio/chem sensing systems, thermal emission control, and tunable filters. GSST is a low-loss phase-change material that can switch from a low-index (n=3), amorphous state to a high-index (n=4.5), hexagonal state with low loss (k<0.3) over a wavelength range of 2-10 microns or more. The GSST thickness can be selected to provide pure phase modulation, pure amplitude modulation, or coupled phase and amplitude modulation. GSST can be switched thermally in an oven, optically with visible light, or electrically via Joule heating at speeds from kilohertz to Gigahertz. It operates with reversible and polarization independent transmission switching over a wide incident angle (e.g., 0-60 degrees).
