Latest Patents
One of his latest patents focuses on "Chemical analysis using dynamic viscometry." This invention relates to a method for determining the reactive state of a chemical reaction process in a reaction mixture, particularly for nucleic acids. The method involves viscosity determination, preferably using a dynamic viscometer. Additionally, the invention includes an improved dynamic viscometer characterized by an appropriate choice of material for the resonator and optimized geometric ratios.
Another significant patent is for a "Pipetting needle." This invention describes a method and a micropipetting apparatus designed to dispense a liquid volume into a vessel via a pipetting needle without any contact between the needle and the liquid contained in the vessel. The method involves forming a drop at the delivery tip of the pipetting needle, which is retained by adhesion forces. The drop is then ejected from the tip by applying a mechanical excitation wave. The apparatus includes an electromechanical transducer that mechanically excites the pipetting needle, along with an electrical signal generator for generating the excitation pulse signal.
