| 摘要 |
A method of controlling the flow of an aqueous fluid in a microfluidic device, which makes use of a fluid gate comprising a UCST (upper critical solubility temperature) polymer and which allows fluid to flow by raising the temperature of the fluid gate above the USCT. Also provided is a device incorporating such a fluid gate and the use of such a device to detect an analyte in an aqueous fluid sample.
