Optical Biosensors & Biophotonics

The Optical Biosensors and Biophotonics Group is led by Dr Tracy Melvin

The group's research is focused on the area of micro and nanofabricated devices for bioanalysis or for biomedical applications. These are either optical, microfluidic (Biological Micro Electro Mechanical Systems abbreviated as BioMEMS), or self-assembled devices.

Our research

Ultrasonic manipulation and transport of DNA molecules in evanescent light fields

Quantum dot switches for biomolecular sensing


Submicron fabrication of biomolecular patterns using optical methods

Optical selection of stem cells: application to human embryonic germ cells

Photonic and microfluidic strategies for the detection of single DNA sequences in serum as methods toward clinical diagnosis

Optical waveguide sensors for highly sensitive detection and quantification of cytokines in biological fluids
