Title: Innovations by Wen-Hwa Chu
Introduction
Wen-Hwa Chu is a notable inventor based in Albany, CA (US), recognized for his contributions to the field of microfabrication. He holds a total of 3 patents, showcasing his innovative approach to developing advanced filtration technologies.
Latest Patents
Wen-Hwa Chu's latest patents include a microfabricated filter with specially constructed channel walls and microfabricated filters utilizing a bulk substrate structure and a thin film structure. These filters are designed with pores defined by spaces between the bulk substrate and the thin film, ensuring uniform width, length, and distribution. The pore width is determined by the thickness of a sacrificial layer, allowing for dimensions smaller than the resolution limit of photolithography. These filters offer enhanced mechanical strength, chemical inertness, biological compatibility, and improved throughput, all while being constructed using relatively simple fabrication techniques. Additionally, he has developed microfabricated containment wells and capsules that utilize these filters for the immunological isolation of cell transplants. The pores in these wells and capsules are sufficiently large to permit the passage of desired biologically-active molecular products while blocking larger immunological molecules, thus providing enhanced biological compatibility and extended useful life.
