Researchers of the ICN2 Nanobioelectronics and Biosensors Group led by Prof. Arben Merkoçi have devised a simple manufacturing method for versatile graphene oxide-based micromotors. Requiring no special equipment, it can be used to produce a range of micromotors that can be further tuned for different purposes. Luis Baptista-Pires explains the process in the paper published in Small.
Graphene photodetectors from Emberion Oy convert light to an electronic signal using graphene charge transducers combined with a nanocrystal light absorber. The photodetectors provide responsivity and low noise over a broad spectral range from VIS to NIR/SWIR wavelengths without cooling below room temperature. The full dynamic range is 160 dB, owing to the low noise and an unsaturated response.
Graphene is made commercially from graphite as multi layers of nanoplates. The highest quality graphene is monolayer however this is expensive to make. A new process has been developed that can make monolayer graphene with very high yield, all it takes is a drop of honey.
