Cell Proliferation Tracking Using Graphene Sensor Arrays
Figure 5
Microdispensing of 50% LB/25% glycerol medium containing E. coli shows it is feasible to guide proliferation to the graphene sensor region. (a) An SEM image shows the graphene sensor and contacts at 80° tilt with a dense circular pattern of adhered bacteria fixed using a dehydration protocol and shown in (b) at a higher magnification.
