Research highlights

A physical model of laser-assisted blocking of blood flow using rectangular radiation pulses
This paper investigates a method for the calculation of blocking blood flow upon treatment of vessel pathologies by laser irradiation using rectangular laser pulses.

A physical model of laser-assisted blocking of blood flow using pulse modulation of radiation
This paper considers amethod for the calculation of blocking of blood flow upon treatment of vessel pathologies by laser irradiation using a series of short radiation pulses.

In vivo sweat film layer thickness measured with Fourier-domain optical coherence tomography
This paper proposes sweat film layer thickness as a potential clinical diagnostic parameter when screening for excessive sweating; a medical condition where the primary site for diagnosis is the palm of the hand

Optical separation of cells on potential energy landscapes: enhancement with dielectric tagging
This paper reviews the emergent techniques of microfluidic sorting of colloidal and cellular samples using optical forces. The results suggest that the methodology of tagging can enhance the sorting of cells.

Researcher profile

Current trends in healthcare have seen a shift towards patient comfort. Ann Singh, a researcher at the CSIR National Laser Centre, is one of the people involved in fundamental research into the development of non-invasive medical techniques and devices, such as determining the optical properties of tissue to contribute to the further advancement of non-invasive cancer therapy research.
