Biophotonics Research

Research in the field of biophotonics is driven by several research teams in universities, university hospitals, corporate research and analysis wings, and other such research institutions. To develop an optical solution, collaborative research projects are required.


Many governments support biophotonic research by establishing funding programs that stimulate advancement and drive collaborative research projects. Funds are being provided to research centers and research projects while supporting networking and knowledge management activities. The number of biophotonic research groups has increased considerably and is still growing across the globe.

Research on cellular and molecular biology

The application of fluorescence spectroscopy, Raman spectroscopy, surface-enhanced Raman spectroscopy, coherent anti-Stokes Raman scattering (CARS), fluorescence, second-harmonic generation (SHG), third-harmonic generation (THG), holography, multifocal optical tweezers, and pico- and femtosecond lasers in the following is being studied:

  • For investigating biomolecular interactions  as in receptor–drug and receptor–ligand, analyzing signal cascades and cellular mechanic properties
  • For identifying specific antigens and receptors
  • For cell mapping
  • For identifying particular cellular state
  • For metabolic product distribution in the cells
  • For description of extracellular matrix
  • For membrane perforation, cell surgery, and optical knockout
  • For division of clear histological areas

Research on POC diagnostics

The use of techniques such as Raman spectroscopy, light-scattering microscopy, and fluorescence measurements (temporal and spectral domain, grouping with antigens) for detecting and identifying pathogens such as virus and bacteria, finding out biomarkers and other metabolic products, and analyzing the composition of body fluids, tissues, cells, and morphological aberrations forms some of the important research areas in point-of-care diagnostics.

Research on clinical imaging

Photonic methods such as optical coherence tomography (OCT), one-photon fluorescence spectroscopy, two-photon fluorescence spectroscopy, Raman spectroscopy, confocal reflection spectroscopy, endoluminal OCT, terahertz spectroscopy, red excitation fluorescence, and CARS (coherent anti-Stokes Raman scattering) approaches are studied for their application in detecting tumors in early stages, intraoperative identification of the borders of tumors, detecting and quantifying caries that are hidden, determining plagues in the blood vessels, monitoring metabolic products and biomarkers, examining fundus of the eye, and studying characteristics of changes in skin such as aging.

Research on therapeutic applications

Optical technologies—femtosecond lasers and excimer lasers—are being studied for their application in precision surgeries such as cornea surgery. Research on using pulsed layers and photodynamic therapy (PDT) for providing selective therapies that are restricted only to abnormal cells is one important field of present research. Studies are being conducted related to the use of nanoparticles and pulsed lasers (with a combination of optical switches) for treatments required at molecular levels as in gene switching. Research on using PDT with other combined methods for its application in novel antimicrobial approaches is an important area of current research.
