Nanofabrication and Microfabrication

Nanofabrication and Microfabrication of Functional Surfaces

Nanofabrication/Microfabrication comprises the use of a set of manufacturing tools based on photolithographic techniques commonly used for making IC or VLSI in the electronics industry. Nanofabrication/Microfabrication is also common key technology in the promising new fields such as MEMS (microelectro-mechannical systems), μTAS (micro total analytical systems), and μFLUMS (micro fluidics and molecules) and has been applied to immune-isolation, drug delivery, biochemical engineering and analytical fields including capillary electrophoresis (CE) . The potential benefits of micro-sized apparatus, relative to systems of conventional size, include reduced consumption of samples and reagents, shorter analysis times, greater sensitivity, portability that allows in situ and real-time analysis and disposability.

Use of nanofabrication/microfabrication methods derived from the semiconductor industry have been adapted to new materials in the recent past to produce electromechanical and fluidic systems in the microscale. Polymers are one such class of new materials as they are considered more suited for biomedical applications due to low cost, abundance, and availability of a wide range of functionality in addition to properties such as low protein adsorption, chemical resistance, and low electrical and thermal conductivities.  Characterization of surface layers with the use of modern experimental methods has acquired special importance owing to extensive investigations in the field of nanostructured materials, as well as functional materials based on quasicrystals.

Our devices which can help in these applications are: All types of contact angle meters used for solid surface, SITA SurfaSpector, A60, A100, A200, A300, RSD100, for liquid or solutions: SITA tensiometers Dynotetser, t15 Plust100SITA ConSpector, SITA Cleanline ST and for surface cleanliness checking and validation: SITA CleanoSpector, SITA FluoScan 3D, SITA Cleanline CI, Viscometer, Rheometer (please discuss with our experts), etc.
