Article Title: Highly Integrated Microfluidic Analyzer for Both Chemiluminescence Immunoassay and Fluorescence LAMP Detection with an Enhanced Cooled CMOS Camera.
Article Snippet: Compared to miniaturized microfluidic chips, their supporting equipment tends to be large and bulky.. Sometimes, it is not even specifically designed for the microfluidic chips..

Article Title: Reconfigurable acoustofluidic platform with vacuum pressure-assisted reversible bonding
Article Snippet: Surface acoustic wave (SAW)–based acoustofluidics enables precise, non-invasive manipulation of cells and fluid flows for a wide range of lab-on-a-chip applications, including biochemical assays, microbiological analysis, cellbased studies, and microscale chemical processing.. In typical SAW devices, a microfluidic channel must be bonded to a piezoelectric substrate to ensure leak-free flow and efficient acoustic coupling.. However, commonly used bonding methods such as plasma, thermal, or adhesive bonding are irreversible, preventing microchannel replacement and leading to cross-contamination during repeated biological or biochemical experiments.

Article Title: Light-programmable mechanical computing via polyaniline composite film
Article Snippet: PDMS film: the PDMS base and curing agent (Sylgard 184, Dow Corning) were mixed at a 10:1 weight ratio and thoroughly blended.
