We present a technique for the simultaneous photostructuring of hydrogels on the μm scale with different compositions on one substrate. The existing methods (e.g. spin-coating of the hydrogel precursor and application of simple molds or spacers) have less potential to integrate spatially separated functional hydrogel dots as needed for the fabrication of complex polydimethylsiloxane (PDMS) on-glass microfluidic chips. Here, we report a method for the fast production of precisely placed hydrogel structures with adjustable height (= 80μm) and width (= 500μm) on glass substrates utilizing black polyoxymethylene molds. The integration of several chambers for different hydrogel precursor solutions in one mold allows the simultaneous photopolymerization of hydrogels with different compositions To visualize the difference in composition of the hydrogel dots and to demonstrate the precision in structuring, various quantum dots were added to the hydrogel precursor solutions and phys. entrapped during the photopolymerization To show the high potential of our photostructuring method, a microfluidic double-chamber reactor was designed and the variability in the performance of tri-enzymic cascade reactions with optionally spatially separated or non-separated enzymes β-galactosidase, glucose oxidase, and horseradish peroxidase was visualized.ABTS Diammonium(cas: 30931-67-0Product Details of 30931-67-0) was used in this study.
ABTS Diammonium(cas: 30931-67-0) belongs to anime. Hydrogen peroxide (H2O2) and peroxy acids generally add an oxygen atom to the nitrogen of amines. With primary amines, this step is normally followed by further oxidation, leading to nitroso compounds, RNO, or nitro compounds, RNO2. Secondary amines are converted to hydroxylamines, R2NOH, and tertiary amines to amine oxides, R3NO.Product Details of 30931-67-0
