Device Fabrication White Paper S2 Jan 2019

Conclusion: The wide application scope of semiconductor based biomedical devices demands precise control over the interaction of bio-analytes with the several surfaces as it passes through the device. This control can only be achieved via modification of surfaces and walls in its components. The properties of the surface and the strategy its modification is determined by the end application, nature of the fluid, composition and target biochemistry. This spread in requirements presents a strong challenge for biomedical device engineering. In this paper, several Oxford Instruments plasma and thermal processing strategies have been described to address this challenge. Next time ... Biosensors are devices that detect biological species and transform the resulting biochemical signal into an physical one that can correlates with the concentration of the target species. These are made up of microfluidics that perform the task of manipulating, processing and transporting analytes in a form that is ready to be processed by these active systems. These active components are commonly fabricated using fabrication processes for electronic, photonic or MEMS based sensors combined with surface functionalization techniques. In the next paper, techniques and challenges for application of such sensors for bio-detection will be outlined.
