Affinity-based detection of biological targets

摘要

A method of biochemical identification by: providing a plurality of capture species bound to one or more substrates and suspected of having one or more biological targets affinity bound to at least one capture species; detecting which capture species contain bound biological targets to generate a binding pattern; and identifying the biological target based on the binding pattern. The capture species are independently selected from the group consisting of antimicrobial peptides, cytotoxic peptides, antibiotics, and combinations thereof. A device having the capture species bound to the substrates. At least two of the capture species are capable of multi-specific binding to one or more biological targets and may have overlapping but not identical affinity properties.
