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.
Graphene-based Sensors
Graphene, a single atomic layer of carbon with a hexagonal crystal structure, is especially appealing for use in sensor applications because of its high surface area and abundance of active sites for analyte capture, favorable semiconductor properties such as high...
Atomic Force Microscopy (AFM)
Atomic Force Microscopy (AFM) is a versatile tool that directly measures and maps intermolecular forces with atomic resolution. AFM is used across a wide range of disciplines to characterize mechanical properties, to generate 3D surface profiles,...
Cell Adhesion
Cell adhesion plays an integral role in cell culture and tissue engineering. In the native environment, cell adhesion molecules (CAMs) bind to the extracellular matrix and neighboring cells to provide structural support and chemical cues vital for...
