The researchers at Tufts University
School of Engineering
demonstrated for the first time a
dissolving electronic implant, made
of silk and magnesium.
It was used to eliminate bacterial
infection in mice by delivering heat
to infected tissue when triggered
by a remote wireless signal. The
devices then harmlessly dissolved.
In vitro studies also showed the
devices could kill bacteria by
releasing antibiotics.
This is an important step forward
for future development of on-
demand medical devices that can
be turned on remotely to perform a
therapeutic function, such as
managing post-surgical infection,
and then degrade in the body.
