Yingxin Deng

Yingxin is a patent agent focused on drafting patent applications and patent prosecution. Her training in bioelectronics and materials science has endowed a diverse scientific background in a variety of fields, including semiconductor devices, biosensors, nano materials, nanotechnology, biopolymers, biomaterials, and electrochemistry. She has 14 publications in top-tier journals with 600+ citations, and presented her work in 10+ U.S. and international conferences.

During her doctoral research, Yingxin investigated the first protonic field effect transistors that controls the flow of protons in hydrated biopolymers, with applications in biological transistors and protonic interconnects for interfacing biosensors. She also invented a breathalyzer with an inkjet-printed organic electrochemical transistor to detect ethanol vapor from breath. She completed her postdoctoral training in chemistry at the California Institute of Technology, where she studied using DNA based biosensors for early detection of lung cancer. Yingxin will draw on her broad knowledge base to assist clients across a range of electronics and materials from medical devices to consumer electronics.
