Photonic Crystal Chemical Sensors and Biosensors
Speaker Dr. Zhongyu Cai
University of Pittsburgh  

 

About the Speaker
Dr. Cai used to work as a research assistant professor and a postdoctoral associate at University of Pittsburgh. He received his BE from Shandong University in 2004 and his PhD degree from National University of Singapore in 2012.  

 

Talk Introduction
Photonic crystals are periodic optical nanostructures that can be used to affect the motion of photons in a similar way the periodicity of a semiconductor crystal affects the motion of electrons. Photonic crystals can find many applications in optical fibers, filters, switches, sensing, energy and environment, etc. In this talk, by using self-assembly methods, I fabricated a variety of high-quality three-dimensional (3D) and two-dimensional (2D) photonic crystals, which were used as platforms for the fabrication of photonic crystal sensors. The photonic crystal sensing technology developed here are easily and inexpensively fabricated to sense a wide variety of analytes, including toxins, pathogens, glucose, metal ions, surfactants and volatile organic compounds. These sensor motifs show very bright diffraction readouts, which may enable visual biological and chemical agents detection in applications such as food safety, healthcare, and chemical threat monitoring.
