PDMS - Wikipedia

SpletDe substraten zijn typisch gecoat in een polymeer zoals polydimethylsiloxaan (PDMS) om de hechting en verspreiding van de nanosferen te bevorderen. De lucht-waterinterfacemethode is gebaseerd op de vorming van een monolaag van nanobolletjes op het oppervlak van een waterbad, op het lucht-waterinterface. SpletUseful properties of PDMS include biocompatibility, gas permeability and transparency. We developed a simple and robust protocol to generate PDMS-based devices using a soft lithography mold produced by 3D printing. 3D chemical gradients were then generated to stimulate cells confined to a micro-channel. maximum transfer speed of usb 2.0
