DNAzymes are precision biocatalysts that destroy unwanted RNA molecules. However, major obstacles to their use in medicine remain. Scientists have now investigated with atomic resolution how DNAzymes work in real time.
A new study shows that flexible brain probes made of graphene micro-transistors can be used to record pathological brain signals associated with epilepsy with excellent fidelity and high spatial resolution.
Physicists have made an important advance in the development of novel materials for spintronics components. These materials may also be the key to quantum computers that are less susceptible to interference.
To overcome the bulkiness of conventional optical diffusers, researchers have applied a layer of specifically designed silicon nanoparticles to a substrate and arranged the particles in a disordered, but carefully planned manner.
Researchers present a completely new type of biomedical tool with a tiny biocompatible, microelectronic micro-catheter equipped with sensor and actuator functions.
The use of graphene-based field-effect transistors is one of the most powerful biosensing units for the detection of numerous biological and biochemical analytes. In new work, researchers propose a microscopic model of mycotoxin detection via graphene-based aptasensors enabling improvement of biosensor sensitivity, which is based on the investigation of aptamer interaction mechanism with graphene channel during binding of targeted molecules. The limit of detection is estimated at only 1 ...
This insight could help researchers understand how and when iridescence first evolved in birds, as well as inspire the development of new materials that can capture or manipulate light.
