Biochemical detection uses specific device architectures and processes. Typical large voltage or current output signals, proportional to the receptor-bound specific biochemical molecule density and its electric charges, are measured. Add-on amplifier devices can further enhance the already high detection sensitivity. Sensor devices may be prepared to simultaneously detect multiple specific biochemical species. Sensor device arrays may be constructed to provide multiple detection means in a single low cost, multi-diagnostic IC chip.
Experimental results are available to support of the invention.
Targeted species examples may include antibodies, DNA fragments, RNA, hormones, co-factors, toxins, bacteria, viruses, bioactive chemicals such as drugs, and other biomolecules that carry electrical charge. Main Advantages Figure 1 shows a typical detection sequence with a controlled set of biochemical species while using the processes described in the patent. The detection tests for IgG, Anti-IgG and then IgG again, confirming and illustrating experimental electronic sensor detection, specificity features and signal strength features.
