| 摘要 |
A method for detecting an analyte in a sample, the method comprising contacting the analyte in a sample with nanoparticles comprising a capture probe for capturing said analyte, the capture probe being configured to act as a centre for controlled aggregation of nanoparticles with said analyte to form an aggregate of predefined form, detecting the analyte by detecting the shape and/or size of the aggregate is provided. Also provided are nanoparticles comprising a capture probe for capturing an analyte, wherein the capture probe is configured to act as a centre for controlled aggregation of nanoparticles with the analyte to form an aggregate of particular detectable size and/or shape, and an assay. |
