Abstract

A microfluidic channel backplane includes a base, and a plurality of microfluidic channels, a sample-adding channel and an enrichment channel that are disposed above the base. Each microfluidic channel of the plurality of microfluidic channels includes a first end and a second end. The sample-adding channel is communicated with first ends of the plurality of microfluidic channels. The enrichment channel includes a first enrichment sub-channel and a second enrichment sub-channel. The first enrichment sub-channel is communicated with second ends of the plurality of microfluidic channels, and one end of the second enrichment sub-channel is communicated with the first enrichment sub-channel.
