Molded Biocompatible and Disposable Pdms/su-8 Inkjet Dispenser
نویسندگان
چکیده
This paper reports on the design, fabrication and demonstration of a polydimethylsiloxane (PDMS)/SU-8 inkjet dispenser with the following novel features: (1) the use of low-cost fabrication process and bio-compatible materials, (2) the use of hydrophobic SU-8 micro-nozzles to limit satellite droplet formation, (3) a modular device design that allows for the reuse of the external actuator, (4) the capability of printing hydrogel constructs, (5) a limited cross-contamination risk as the device is disposable, (6) and the potential for integration with other PDMS microfluidic systems. The device successfully dispenses droplets with diameters ranging from 80-130μm at rates of 2-1000 droplets/second.

Lab-on-a-printer Platform Technology
This work introduces and demonstrates the concept of Lab-on-a-Printer whereby microfluidic components are integrated with inkjet dispensers. This concept allows for multi-functional microfluidic materials processing to be performed on chip and direct post-process printing of those materials enabling printing of programmable gradients and more generally structures with programmable composition. ...
متن کاملLow-cost Flexible All-inkjet-printed Microfluidic Sensor
This paper demonstrates a novel and low-cost additive manufacturing process for flexible and disposable microfluidics on virtually any substrate, with which the first “all-inkjet-printed” microfluidic microwave sensor is prototyped. A 30-μm-high 600-μm-wide SU-8 (polymer) 3-D microfluidic channel and an electromagnetic sensing setting are fabricated with sole reliance on multilayer inkjet-print...

In this contribution we describe the application of Ink-Jet printing and Stencil Lithography in bionanotechnology. Both techniques are alternative patterning methods that can be used for the fabrication of biocompatible microand nanostructures out of the costly and restricted clean room environment. The applications presented in this contribution are 1) the cell patterning using Au dot arrays d...
متن کاملIn vivo evaluation of biocompatible intravascular stents coated by inkjet printing
Inkjet–printing technology was used to apply biodegradable and biocompatible polymeric coatings of poly(D, L lactide) with the antiproliferative drugs simvastatin (SMV) and paclitaxel (PCX) on coronary metal stents. A piezoelectric dispenser applied coating patterns of very fine droplets (300 xL) and ink jetting was optimized to develop uniform, accurate and reproducible coatings of high yields...
