Abstract
In some embodiments, a method includes applying an analyte to a rGO biosensor configured to bind to the analyte; applying a DC voltage to the rGO biosensor, wherein the DC voltage is +0.0008V to +0.005V for a negatively charged analyte; or −0.005V to −0.0008 for a positively charged analyte; and monitoring an electrical signal from the rGO biosensor for a response to the analyte.
Claims19
A method comprising:
- applying a sample to a rGO biosensor with a bioreceptor configured to bind to an analyte;
- applying a DC voltage to the rGO biosensor, wherein the DC voltage is:
- +0.0008V to +0.005V for a negatively charged analyte;
- or
- −0.005V to −0.0008 for a positively charged analyte;
- and
- monitoring an electrical signal from the rGO biosensor, wherein a peak in the electrical signal indicates the sample includes the analyte.
