Graphene structure is going to receive a new dimension altogether. The researchers from the New York University Tandon School of Engineering and NYU Center for Neural Science have recently found a technique of building ultra-small, ultra-sensitive electrochemical sensors with homogenous and humdrum properties which are by engineering graphene structure on an atomic level.
The biological cell-like translucently tuned electrochemical sensors are of great value to environmental monitoring systems and medical diagnostics. The development of the nanoengineered carbon-based electrodes is soaring as it provides thermal, unmatched electronic, and mechanical properties. The need for knowledge regarding the quantitative principles for the accurate development of the electrode sensitivity for biochemical molecules has yet to be explored. The effects of structural defects in graphene on the electrode sensitivity have helped current researchers precisely engineer and produce uniform arrays of graphene electrodes for the industrial scale. The graphene is a carbon atom-thin sheet that helps understand the relation between structural defects and electrode sensitivity. The team has been able to find that a defect in a specific group can help yield a desired sensitive electrode.
The current study can help improve the fabrication as well as applications for graphene-based electrodes techniques. The traditionally used carbon-based electrodes have to be attuned for sensitivity post-fabrication that is a time-captivating process affecting the large-scale production, but the researchers’ new study can aid in accurately engineering the sensitivity at the time of the material synthesis thereby enhancing industrial production. The use of carbon-based electrodes for applications necessitating a dense array of sensors tends to give unreliable results owing to the electrode sensitivity variations due to large variations of the electrode. This new study can help generate ultra-small carbon-based electrodes with homogenous and highly sensitive in the next-generation neural probes, drug development, optical methods replacements, or medical diagnostics. Zahra Talebi Esfahani from Payame Noor University has confirmed the new spintronics applications can help stem from commencing holes into graphene so as to form triangular antidot lattices and grant the material innovative magnetic properties. This novel material can replace the silicon chips in order to prove fruitful for nanoelectronics.
