Silk-Based Printable,
Wearable, Biosensors
Tufts University scientists have developed biopolymer-based
sensors that glow when dangers are present and can be printed
on almost anything.

have devel " Our
sensing method can
monitor in real time what's
happening in the environoped
a way to detect bacteria, toxins,
and dangerous chemicals in the environment
using a biopolymer sensor
that can be printed like ink on a wide
range of materials, including wearable
items such as gloves, masks, or everyday
clothing. It can even be embedded in
drones to sense trace levels of airborne
SARS-CoV-2, or it could be modified to
adapt to whatever the next public
health threat might be.
The sensor, which is based on computationally
designed proteins and silk
fibroin extracted from the cocoons of
the silk moth Bombyx Mori, can also be
embedded in films, sponges, and filters,
or molded like plastic to sample
and detect airborne and waterborne
dangers, or used to signal infections or
even cancer in our bodies.
These sensors are a big leap from
other approaches to measuring pathogens
or chemicals in the environment,
which often rely on biological components
that degrade quickly and require
careful storage. The sensors also do not
depend on electronic components that
can be difficult to integrate into flexible
wearable materials.
To learn more about this, I interviewed
two of the researchers, Fiorenzo
Omenetto, Frank C. Doble Professor of
Engineering and director of the Tufts
Silklab, and Giusy Matzeu, a former research
professor at the Silklab.

ment. It can also detect what can
occur in the human body by monitoring,
in a non-invasive way, biological
fluids like saliva or breath, " said Matzeu.
The active component of the biopolymer
sensor, which was developed
by David Baker, Henrietta and
Aubrey Davis Endowed Professor in
Biochemistry at the Institute for Protein
Design at the University of Washington,
is a molecular switch designed using
molecular dynamics techniques and
artificial intelligence. These molecular
switches have been made of synthetic
proteins that act like a lock and key,
in a cage, and are sensitive to a particular
analyte.
When a virus, toxin, or other target
molecule comes near, it binds to the
