1. A method of detecting a plurality of targets in a biological sample, comprising:
- (a) contacting the biological sample with a plurality of target-binding probes to form a plurality of target-bound probes;
(b) covalently attaching at least one of the target-bound probes to the biological sample;
(c) observing a first set of signals from a first set of the plurality of target-bound probes;
(d) modifying the observed signals;
(e) generating a second set of signals from a second set of the plurality of target-bound probes; and
(f) observing the second set of signals.

Abstract
Methods for detecting a plurality of targets in a biological sample are provided. The method comprises contacting the biological sample with a plurality of target-binding probes to form a plurality of target-bound probes, covalently attaching at least one of the target-bound probes to the biological sample, and observing the signals from the target-bound probes sequentially. An associated kit and device for detection of the plurality of targets are also provided.
