The US Department of Energy has launched

on-line searchable database of science, technology, and engineering
research information. Entering the word “sensor” produces over

University of
Pennsylvania
researchers
have developed an innova-
tive sensor for detecting
Lyme disease, which typically
develops antibodies so slowly
that serological diagnosis is difficult. The new sensor binds Lyme
antibodies to carbon nanotubes, which are converted to transistors.
After being exposed to liquids containing Lyme bacterial proteins, the
electrical properties of the sensors change; sensitivity is more than
sufficient to detect the Lyme disease bacterium in the blood of re-
cently-infected patients
.
US Navy Research Lab scientists have fabricated the sensor
using a single monolayer of molybdenum disulfide (MoS2) on a silicon
dioxide wafer. It functions effectively as a chemical vapor detector,
exhibiting highly selective reactivity to a range of analytes. The sensor
is sensitive to triethylamine a chemical associated with theV-series
nerve gas agents, but does not respond to a lot of common non-
harmful chemicals that would otherwise give a lot of false alarms.
