Methods comprising the use of photoactivated chemical bleaching for detecting multiple targets in a biological sample are provided. The methods include the steps of binding at least one probe to one or more target present in a biological sample including multiple targets, and detecting a signal from the probe. The method further includes the steps of contacting the sample comprising the bound probe with a photoinitiator and irradiating the sample, thereby initiating a photoactivated chemical bleaching process that substantially inactivates the probe. The method further includes the steps of binding at least one probe to one or more target present in the sample, and detecting a signal from the probe. The process of binding, detecting and bleaching may be iteratively repeated.
