Latest Patents

Hui Hui Zeng holds a patent for an "Excitation ratiometric fluorescent biosensor for zinc ion at picomolar levels." This invention presents a highly selective and sensitive method for measuring zinc ions using a carbonic anhydrase-based approach. The technique utilizes an excitation ratiometric format based on resonance energy transfer, where the zinc ion level is transduced as the ratio of fluorescence intensities excited at two different wavelengths. This method is particularly effective in fluorescence microscopy formats, achieving a detection limit of about 10 pM in zinc buffered systems. This represents a ten to one thousand-fold improvement over traditional Fura indicators, which also respond to calcium and magnesium, and a one hundred thousand-fold improvement over the recently described FuraZin-1.
