SERS Chip Senses Near the Quantum Limit

Facebook Twitter LinkedIn Email Comments
BUFFALO, N.Y., Jan. 13, 2021 — University at Buffalo researchers have developed a chemical sensing chip that boasts a range of potential applications, from the detection of illicit substances and dangerous materials, to counterfeit prevention. The chip, which relies on surface-enhanced Raman spectroscopy (SERS), supports incorporation into hand-held sensor devices and approached quantum-limit sensing capabilities — a challenge for many conventional SERS chips — in testing. Qiaocqiang Gan, a professor of electrical engineering, led the team that introduced the chip. The team’s work builds on a...Read full article
