Archer Exploration has printed and patterned ink formulations of human antibodies on graphene-based biosensor components derived from the company’s Campoona graphite.

“One of the biggest challenges to printable biosensors involves the scalable fabrication of integrated componentry capable of multiplexing – detecting a number of different diseases simultaneously using the same specimen. The development of printable biosensors is envisioned to impact industries servicing human health, including point of care diagnostics and medical devices.
 
Archer has patented a potential solution to printable biosensors capable of multiplexing. This
solution involves the use of graphene, the thinnest material known which provides an
ultrasensitive biochemical interface.”…
 
“Biosensors can reduce patient (end-user) wait times by bypassing traditional infrastructure requirements and lengthy testing processes in disease management. Biosensors form part of the growing $300+ billion revenue global biotechnology industry.”

 
From ASX announcement Human antibodies printed on graphene biosensors.

“Archer reports that ink formulations comprised primarily of human antibody immunoglobulin G (IgG) as the active constituent were successfully prepared and printed using proprietary methods.
 
The IgG inks were printed on resin-coated paper and a number of graphene-based electrodes and were able to withstand the chemical and physical processes in the formulation, printing, and post-printing steps.
 
Biological sensor devices are used in the detection and diagnosis of disease. The uniqueness of a biosensor is that its critical components are integrated into one sensor.
 
One of the biggest challenges to printable biosensors involves the scalable fabrication of integrated componentry capable of multiplexing – detecting a number of different diseases simultaneously using the same specimen. The development of printable biosensors will hopefully impact industries servicing human health, including point of care diagnostics and medical devices.”
