1. A microfluidic system for detecting a biological entity in a sample volume, the microfluidic system comprising:
- a chamber configured to receive the sample volume, wherein the chamber comprises a detection region for detecting the biological entity;
a first port in fluid communication with the chamber; and
a second port comprising a filter in fluid communication with the chamber; and
wherein a fluid provided to the first port or the second port flows between the first port and the second port through the chamber such that the fluid provided to the first port passes the sample volume through the detection region and the filter to retain the biological entity at the filter, and the fluid provided to the second port transfers the biological entity retained at the filter to the detection region.
