The sensing capability of graphene is quite stunning and is only now beginning to be leveraged in advanced micro-device designs for the future, particularly in life science applications.
“Single atom thick sheet graphene, with its conductivity, strength and surface to volume ratio advantages, lends itself well to what today seem like futuristic applications in the wearables, sensing and bio-detecting fields, just to name a few….
The field of biosensing is one of the first areas where single layer graphene is being leveraged for its advanced performance capabilities. Graphene based hand held blood analyzers about the size of a smart phone that a doctor could use in the field to real time detect diseases are already available.
Companies like Nanomedical Diagnostics have been characterizing diseases such as Lyme disease and Zika virus with such a tool. The sensitivity, stability and small scale of graphene makes this kind of mobility and instantaneous feedback possible.
Doctors can now take blood analysis out to remote destinations and get immediate feedback for treating patients in desolate areas, thousands of miles from conventional medical care.
“But this atomic level sensing performance can be enhanced even further when the graphene layer is combined with ‘white graphene’ or hBN….
Layering graphene on top of hBN when building silicon-based biosensors could enable such breakthroughs as using the perspiration from one’s skin in a resting state to real time monitor glucose levels and many other aspects of one’s health – all simply by wearing a patch, a bracelet or a properly outfitted garment.
The potential of this combination is only just starting to be appreciated. The graphene producers and users that have the ability to characterize and implement these materials together can provide real unique value to sensing device makers and will establish performance capabilities to enable new fields that haven’t even been thought of yet…. “
The sensing capability of graphene in the healthcare sector has enormous potential. For example Graphene ink for diabetes monitoring
