Scientists create smart bioelectronics that respond to light and heat
Researchers have designed programmable bio-electrodes that switch on and off in response to light and temperature, enabling them to perform logical operations like computer circuits. The breakthrough could accelerate development of intelligent medical implants and biosensors that adapt to changing body conditions without external power sources.

<p>The ability to program and mimic the dynamic microenvironment of living organisms is a crucial step towards the engineering of advanced bioelectronics. Here, we report for the first time a design for programmable bioelectronics, with ‘built-in’ switchable and tunable bio-catalytic performance that responds simultaneously to appropriate stimuli. The designed bio-electrodes comprise light and temperature responsive compartments, which allow the building of Boolean logic gates (i.e. “OR” and “AND”) based on enzymatic communications to deliver logic operations.</p>
