Biophotonics is a novel field that relies on the results of lasers to move particles of matter into certain organizational structures, like a three-dimensional chessboard, or hexagonal arrays. It is responsible for the development of methods that complement the range of current imaging and therapeutic techniques in widespread clinical use.
Therapeutic biophotonics: Applications of light include the treatment of diseases by altering biological processes. Light is employed for modifying the cellular functions photochemically and to eradicate tissues by the photomechanical or photothermal process.
Photomechanics: Photomechanical analyses are based on optics used to study the gradient properties in biological materials. They is also used for examining the connection between mechanical stress and strain in the structure of root dentin. Light-sensitive particles in polymer solutions or solids will undergo a conversion from light to mechanical energy called photo contraction.
Fiber optic sensors: This technique deals with remote sensing of physical and chemical specifications. By focusing light into the central part and directing to a sample, analytical information is obtained. The optical signals are reflected back across an equivalent fiber and therefore the intensity is calculated. It is broadly accepted in detecting clinical and biochemical analytes, e.g., metabolites, immunoproteins, enzymes, and serum electrolytes. Sensors that react to those parameters are often called biosensors.
