System for detecting electrical properties of a molecular complex
First Claim
1. A method for detecting electrical properties of a molecular complex, comprising:
- electrically coupling an electrode to a molecular complex that outputs an electrical signal affected by an electrical property of a molecular complex, wherein the effect of the electrical property of the molecular complex on the electrical signal is characterized by an expected bandwidth;
receiving the electrical signal from the electrode;
selectively amplifying and integrating a portion of the electrical signal over time within a predetermined bandwidth, wherein the predetermined bandwidth is selected at least in part based on the expected bandwidth;
comparing the selectively amplified and integrated electrical signal to a threshold; and
outputting an indication that the selectively amplified and integrated electrical signal has reached the threshold;
initiating the integrating based on an initiation flag; and
terminating the integrating based on the indication.
