Sample analyzing chip

摘要

The present invention relates to a sample analyzing chip. The chip can prevent upper and lower substrates of a channel from being attached to each other due to deflection on a micro channel and can solve the problem of the sample drying up within a measuring time of a target. Also, the chip can prevent bubbles from being generated in a central portion of the micro channel.

主权项

1. A sample analyzing chip comprising:
a micro channel formed between an upper substrate and a lower substrate bonded to each other, and including a micro pillar and a bubble prevention channel; an inlet formed at one side of the micro channel, and including a first bottleneck configured to control a flow and a flow rate of an injected sample and delay drying of the sample; and an outlet formed at another side of the micro channel, and including a second bottleneck configured to delay flowing of the sample out from the micro channel and drying of the sample.
