Abstract: A plural color broadband coherent anti-Stokes Raman scattering (CARS) microscope includes: a first light source to produce a first light including a narrowband radiation; a second light source to produce a second light including a broadband radiation; a third light source to: receive the first light from the first light source; receive the second light from the second light source; and produce a third light comprising the narrowband radiation and the broadband radiation by combining the first light and the second light such that the first light and second light are spatially overlapped and temporally overlapped; and a primary objective to: receive the third light from the third light source; communicate the third light to a sample; and subject the sample to simultaneous interpulse CARS stimulation and intrapulse CARS stimulation by irradiation with the narrowband radiation and the broadband radiation in the third light.

Abstract: Methods and systems are described for suppressing nonresonant background in broadband coherent anti-Stokes Raman scattering (CARS) microscopy and spectroscopy. The methods and systems improve sensitivity and signal to noise ratio in CARS.

Abstract: The stabilization of biomaterials such as proteins in a nominally dry, hydrophilic glassy matrix is vastly improved by the addition of an appropriate amount of a small-molecule pasticizer such as a glycol or DMSO to the formulation, while maintaining a glass transition temperature (Tg) that is above the storage temperature. By plasticizing the glasses, their ability to preserve proteins is improved by as much as 100 times over the unplasticized glass at room temperature. The plasticizer confers the greatest beneficial effect when it is dynamically coupled into the bulk glass, and this coupling occurs over a fairly narrow range of plasticizer concentration. Methods are described in which a small-molecule plasticizer can be incorporated into a glass made of much larger molecules (e.g. a polymeric glass), with desired dynamic coupling, via a molecule that is believed to act as a dynamic linker. Protein preservation data was obtained from two enzymes, horseradish peroxidase (HRP) and alcohol dehydrogenase (ADH).
