  • Patent number: 11940380
    Abstract: Systems and methods for sensing vibrational absorption induced photothermal effect via a visible light source. A Mid-infrared photothermal probe (MI-PTP, or MIP) approach achieves 10 mM detection sensitivity and sub-micron lateral spatial resolution. Such performance exceeds the diffraction limit of infrared microscopy and allows label-free three-dimensional chemical imaging of live cells and organisms. Distributions of endogenous lipid and exogenous drug inside single cells can be visualized. MIP imaging technology may enable applications from monitoring metabolic activities to high-resolution mapping of drug molecules in living systems, which are beyond the reach of current infrared microscopy.

  • Patent number: 11933746
    Abstract: A device to host a crystallization medium, such as a solution, for crystal growth and a system for X-ray diffraction experiments to determine the atomic structure of crystals. A plurality of cells have a well, a sample holder placed in the well. The solution is hosted in the sample holder between thin-plates or one thin-plate. A cap seals an opening to the cell and each sample holder can be extracted independently from each well. A system for automated X-ray diffraction experiments for small crystals in the sample holder extracted from the wells utilizes an ultrasonic acoustic levitator to determine the crystal structure at atomic resolution. X-ray diffraction images are generated by scanning the X-ray beam over the levitated sample holder along a spiral trajectory by rotating the sample holder and moving in the direction perpendicular to the X-ray beam and the rotation axis at the same time.
