Chou group has two primary missions: (i) explore innovative applications of nanotechnologies in information (electronics, photonics, magnetics, etc.), bioengineering, and energy (solar cells, light emitters, etc.) by combining cutting-edge nanotechnology with frontier knowledge from different disciplines; and (ii) to develop new nanofabrication technologies that will fabricate structures substantially smaller, better, and cheaper than current technology permits.

Nanotechnology offers great opportunities for significant discoveries and revolutionary innovations in broad disciplines, because many conventional theories no longer apply in nanoscale.

Chou group’s current research focus on three areas: 

  1. Nano-bioengineering (biosensing, diagnostics, and personal health)
  2. Nanophotonics (sub-wavelength optical elements (SOE) that has a working principle fundamentally different from bulk optics and enables an optical system flat and with a thickness less than paper thick), and
  3. Nanofabrication

Dr. Chou's four-decade research spans several different fields: nanotechnology (including electrical, optical, magnetic, and biological), bioengineering, and medical diagnostics. His work and inventions have significantly impacted both academia and industry, and have created new research fields and new industries and business.

Dr. Chou’s most well-known inventions  include: nanoimprint - a new paradigm in nanopatterning that has become a multi-billion dollar industry, 7 NM grate-wrap-around transistors/memories, lithographically-induced-self-assembly (LISA), single domain-patterned-media (quantized disk) - a new paradigm in magnetic data storage, new nanophotonics (e.g. sub-wavelength optics, ultra-sensitive Raman and fluorescence sensors, nanoplasmonic LEDs, and solar cells), nanochannel single DNA molecule analyzer, a new ultra-sensitive biosensor (D2PA), and a game-changing new instant mobile self-test (iMOST) platform.
