Surface Modification of Microfluidic Devices
Microfluidic systems are widely used for the separation, detection, and analysis of biochemical reagents. Their miniaturized architecture offers several advantages, such as higher sample throughput and processing rates, low manufacturing costs, advanced system integration, and reduced volumes of samples and...
Chemical Vapor Deposition Copolymerization
Chemical vapor deposition (CVD) has been used to polymerize various derivatives of [2,2]-paracyclophane. This creates a reactive coating of poly(p-xylylene) on a surface. We can alter the surface properties by changing the paracyclophane functional group. CVD produces thin, uniform...
Dynamically Switching Surfaces
Our research on reversibly switching surfaces was featured in an article in Science (J. Lahann, et al., A Reversibly Switching Surface, January 17, 2003, 299, 371-374.) These "smart surfaces" can reversibly switch properties in response to an external stimulus. To...
Advanced Polymer Coatings
We are currently developing a novel class of polymers with potential for biomimetic and spatially directed surface engineering. This Òreactive coatingÓ technology uses chemical vapor deposition (CVD) polymerization to deposit a wide range of chemical signatures on various substrate materials....
