Alter Surface Chemistry
The ability to control and tailor surfaces with specific chemical functionalities is oftentimes critical for studying surface interactions of materials or improving interfacial, biological, and electronic properties for optimal material performance. Depending on the process gas and processing conditions used, plasma can alter the surface to be more hydrophilic or hydrophobic, or to introduce specific chemical functionalities to the surface without affecting the bulk material. This page provides brief summaries on the application of plasma treatment to alter surface chemistry.
Microcontact Printing
Microcontact printing (µCP) transfers molecules from a soft, patterned stamp to a surface, the way an office rubber stamp transfers ink to paper, but with features down to a few microns. Since its introduction in the Whitesides lab it has become a...
QCM-D Sensor Cleaning
Quartz crystal microbalance with dissipation monitoring (QCM-D) detects nanogram changes in mass and softness at a sensor surface. That sensitivity cuts both ways: a few nanometers of leftover organics from storage, handling or the last experiment...
Microcantilever and Resonator Sensors
Microcantilevers, nanomechanical resonators and acoustic-wave devices turn molecular events into measurable signals: a shift in resonant frequency, a change in surface stress, a bend of a few nanometers. At that scale the sensor surface is part of...
Polycarbonate Microfluidics
Polycarbonate (PC) is a widely used engineering thermoplastic in microfluidics and lab-on-a-chip systems, valued for its high optical transparency, exceptional impact strength and toughness, dimensional stability, and a high glass transition...
