Systems and methods for post-treatment of dry adhesive microstructures
Provided are systems and methods for the post-treatment of dry adhesive microstructures. The microstructures may be post-treated to comprise mushroom-like flaps at their tips to interface with the contact surface. In some aspects, a change in material composition of the microstructures in a dry adhesive may affect mechanical properties to enhance or diminish overall adhesive performance. For example, conductive additives can be added to the material to improve adhesive performance. In other aspects, microstructures comprising conductive material may allow for pre-load engagement sensing systems to be integrated into the microstructures.
Anti-wetting coating for Si-based MEMS fluidic device, and method of application of same
A photo-patterned fluorocarbon monolayer directly grafted to Si surface atoms provides anti-wetting performance at controlled locations, wherein the Si surface oxide is etched and reacted with fluorocarbon chains with a terminal CC double bond, resulting in SiC surface. As the direct SiC linkages are chemically robust, and much more resistant to decomposition than SiOC bonds, the resulting surface does not suffer from the shortcomings of current MEMS dispensers.

Methods of forming an integrated device, and in particular forming one or more sample wells in an integrated device, are described. The methods may involve forming a metal stack over a cladding layer, forming an aperture in the metal stack, forming first spacer material within the aperture, and forming a sample well by removing some of the cladding layer to extend a depth of the aperture into the cladding layer. In the resulting sample well, at least one portion of the first spacer material is in contact with at least one layer of the metal stack.
