Latest Patents

One of his latest patents is titled "Microfluidic interface for highly parallel addressing of sensing arrays." This invention discloses a spotter device and methods for the formation of microassays, biochips, biosensors, and cell cultures. The spotter is designed to deposit highly concentrated spots of protein or other materials on a microarray slide, wafer, or other surfaces. It can also perform various chemistry steps on the same spots. The device increases the surface density of substances at each spot by directing a flow of the desired substance over the area until surface saturation is achieved. The spotter can be loaded by well plate handling equipment and utilizes wells, microfluidic conduits, and orifices to deposit proteins, biomolecules, or chemicals on a separate surface. Each orifice is connected to two wells via microconduits, forming a seal when the spotter contacts a surface. This innovative device is particularly useful for depositing proteins in high concentrations, as it can remain on a surface for extended periods.
