Surface enhanced Raman scattering of herpes simplex virus in tear film.

Conjunctivitis is currently diagnosed using white light microscopy of corneal or conjunctival cells in culture. This takes time and is subjective. An ideal test would be sensitive, specific, near-patient and quick.

Photodiagnosis using Raman and surface enhanced Raman scattering of bodily fluids.

Raman spectroscopy is the measure of inelastic scatter and has been described since 1928. It is particularly useful for medical applications because the scattered radiation measured is unique for each biomolecule. The aim of this study was to review works published in Raman scattering and surface enhanced Raman scattering (SERS) on bodily fluids.

Clinical aspects of photodynamic therapy.

Photodynamic therapy is a method for local destruction of tissue or organisms by generating toxic oxygen and other reactive species using light absorbed by an administered or an endogenously generated photosensitiser. It is a highly promising treatment for patients with cancer. More recently it has found increasing use as a method of therapy for non-cancerous illnesses.
