Latest Patents

One of his latest patents is the "Hemoglobin A1c-specific aptamer, hemoglobin-specific aptamer, and applications thereof." This invention provides aptamers that were selected in vitro using SELEX and a microfluidic chip system. The aptamers exhibit low free energy, making them more stable than conventional antibodies. Their high specificity to Hemoglobin A1c or Hemoglobin allows for effective use in diagnosing diabetes and/or anemia.

Another significant patent is the "High-efficiency multiple-pass nonlinear optical wavelength converter with an electro-optic phase compensator and amplitude modulator." This invention employs a variable dispersion element between adjacent passes of a nonlinear wavelength conversion process. Controlled by voltage via the electro-optic effect, the variable dispersion element dynamically alters the phase matching condition, thus modulating the laser output amplitude. When the phase mismatch is compensated, the converter achieves maximum efficiency.
