Cloth-based microfluidic analytical devices by laser-induced hydrophilization technique
Sensors and Actuators B: Chemical, 2021Abstract In this work, we reported a new method for preparing microfluidic cloth-based analytical devices (μCADs) by simple chemical treatment and laser scanning. The mechanism of creating superhydrophobic-superhydrophilic patterns in cloth surfaces was investigated.

Analytical Chemistry, 2021
A microfluidic magnetic analyte delivery (μMAD) technique was developed to realize sample preparation and ultrasensitive biomarker detection. A simply designed microfluidic device was employed to carry out this technique, including a poly(dimethylsiloxane)-glass hybrid microchip having four straight rectangular channels and a permanent magnet.

Bioanalysis faces challenges in achieving fast, reliable, and point-of-care (POC) determination methods for timely diagnosis and prognosis of diseases. POC devices often display lower sensitivity compared to laboratory-based methods, limiting their ability to quantify low concentrations of target analytes.
