Burn injuries are a major public health issue and their management is a key concern. Regular assessment of healing tissues is necessary but biopsies are painful and may hinder the healing process. Now, a group of Indian scientists have come up with a solution for easier assessment of healing progression, using laser light.
Scientists at Manipal University in Karnataka have demonstrated the ability of the laser-induced fluorescence (LIF) technique to quantify the amount of collagen in healing tissues and thus analyse the recovery process: the more the collagen content, the healthier the tissue.
The strategy is to study biochemical changes by exploiting tissue fluorophores or chemical compounds that can re-emit light upon light excitation. Some of the most common fluorophores are collagen, elastin, amino acids (building blocks of proteins) such as tryptophan, phenylalanine and tyrosine that are responsible for tissue autofluorescence....Read more
