Graphene sensor rapidly detects opioid metabolites in wastewater

The unique properties of the atom-thick sheet of carbon, known as graphene, enabled a new penny-sized, multiplexed bio-sensor that's the first to detect opioid byproducts in wastewater, a team of researchers from Boston College, ...

Building artificial nerve cells

For the first time, researchers have demonstrated an artificial organic neuron, a nerve cell, that can be integrated with a living plant and an artificial organic synapse. Both the neuron and the synapse are made from printed ...

The first topological acoustic transistor

Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials ...

Biosensors using field-effect transistors show great promise

Demand for sensitive and selective electronic biosensors—analytical devices that monitor a target of interest in real time—is growing for a wide range of applications. They are ideal for health care within clinical settings, ...
