Rapid and sensitive detection of molecular biomarkers is extremely important in many clinical applications including cancer diagnosis and treatment evaluation, as well as emergent care. The biomarker optical sensing market has been growing as fast as photovoltaics in recent years. However, most of the well-developed bio-optical sensing instruments, to date, are still on the high-end of the market. They are expensive, bulky and require dedicated personnel and lengthy turnaround times to operate, which is unsuitable for point-of-care applications.
We are developing label-free bio-optical sensing chips which are low cost, compact, portable and high sensitivity. The chips consist of surface plasmon resonance devices on disposable fiber tips, porous materials and microfluidics.
