Sensors
Quantum-Limit-Approaching Chemical Sensing Chip
The chip can quickly and accurately identify drugs and other trace chemicals.
University at Buffalo, NY
R
esearchers developed a chemical
sensing chip that could lead to handheld
devices that detect trace chemicals
- everything from illicit drugs to pollution
- as quickly as a breathalyzer identifies
alcohol. It also may have uses in
food safety monitoring, anti-counterfeiting,
and other fields where trace chemicals
are analyzed.
Using surface-enhanced Raman spectroscopy
(SERS), when biological or
chemical molecules land on the chip's
surface, some of the captured light interacts
with the molecules and is " scattered "
into light of new energies. This
effect occurs in recognizable patterns
that act as fingerprints of chemical or biological
molecules, revealing information
about what compounds are present.
Because all chemicals have unique
light-scattering signatures, the technology
could eventually be integrated into a
handheld device for detecting drugs in
Au
Ag

chemicals are analyzed. (Image: Huaxiu Chen, University at Buffalo)
DEPARTMENT OF DEFENSE
MAINTENANCE SYMPOSIUM
DECEMBER 18-21, 2023
SAN DIEGO CONVENTION CENTER, SAN DIEGO, CA
Over 2,000 maintainers from military, government, industry, and academia are expected to converge at the Symposium
in San Diego in 2023. The foremost leading experts from across the sustainment enterprise are anxious to share their
ideas and strategic visions. This year's agenda will focus on integrated sustainment in a contested environment by
exploring agile combat sustainment, the organic and commercial industrial bases, resilient software capabilities, data
analytics, artificial intelligence, maintenance manpower, and much more. Additionally, don't miss out on the Symposium's
inspirational, high-energy, annual Secretary of Defense Maintenance Awards Banquet and Ceremony to recognize and
congratulate the Department's best maintainers.
Participate, speak-up, tell your story, ask tough questions, and expand your professional network...don't sit quietly
admiring the problem, standup and be part of the solution.
