Researchers have developed a novel nanoscale device for detecting DNA biomarkers. The device preconfines translocating molecules using an ultrathin nanoporous silicon nitride membrane separated from a single sensing nanopore by a nanoscale cavity.
Scientists show that nanofibers can provide a link between far-flung atoms, serving as a light bridge between them. The new technique could eventually provide secure communication channels between distant atoms, molecules or even quantum dots.
Experimentalists have found evidence that the spin-orbit coupling induced in graphene by proximity to transition metal dichalcogenides affects electron spins differently depending on their orientation. This work suggests new approaches to controlling the transport of spin and valley information in future spintronics devices.
For decades, scientists have been trying to make a true molecular chain: a repeated set of tiny rings interlocked together. In a new study, researchers announced the first confirmed method to craft such a molecular chain.
Researchers are using magnetic fields to influence a specific type of bacteria to swim against strong currents, opening up the potential of using the microscopic organisms for drug delivery in environments with complex microflows - like the human bloodstream.
Researchers have managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule?s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold.
