Abstract: A highly sensitive thermally stimulated emission (TSE) spectrometer, and a method of conducting spectrometry, are described. Provided is a thermally stimulated emission (TSE) spectrometer comprising a cryostat housing a sample stage in an area; a cooling source configured to lower a temperature of the area to as low as 9 K; a photo-excitation source configured to deliver electromagnetic radiation to a sample on the sample stage; a heat source configured to heat the area; a temperature control unit configured to control the cooling source and the heat source, so as to cool or heat the area; a monochromator configured to receive light emitted from the sample on the sample stage as the area is being heated by the heat source, and emit a specific wavelength or wavelengths of the light; a highly sensitive photomultiplier tube (PMT) configured to detect the light emitted from the monochromator at the specific wavelength or the light emitted directly from the sample covering all wavelengths.

Abstract: A method and apparatus for detecting more than one fluorophore in a sample. A broad spectrum excitation light is passed through a shaping filter before illuminating the target sample with more than one fluorophore to be detected, where the optical density of the shaping filter changes based on the wavelength of the broad-spectrum excitation light passing through it.
Abstract: Protein rupture under compressive forces can be regulated by cations. More specifically, pico-Newton forces can cause rupture of protein molecules, as shown in examples with calmodulin (CaM) and tau proteins, among others. However, rupture does not occur in the presence of various concentrations of cation(s), thus elucidating new targets for disease therapy and providing therapies for neurodegenerative diseases or other conditions involving protein misfolding, dysfunction, or aggregation.
Abstract: Uronate-containing polysaccharide hydrogels that can be photo-patterned are described. The method involves forming a hydrogel and imetal-coordinating it with a reducible metallic cation and exposing the hydrogel to light in a desired pattern. The exposure to light reduces the metallic cation and results in an irreversible change in the elastic moduli and pore size of the irradiated portions of the patterned hydrogel. The method aha the benefit of allowing the user to produce such a hydrogel in any pattern desired. Patterned hydrogels and cell substrates formed by this method are also described.
