  Biophotonic techniques are growing in rapid rhythms enabling the monitoring
of subcellular structures and non-invasive theranostic interventions in cancer
and autoimmune diseases. The integration of Biophotonics with nanotechnology
and biosensors brings a revolution in the micro- and nano-world with new
optical tools. Among them, optical tweezers revive as a potential tool for
tracking cells behavior and probing interactions forces between cells,
cells-biomolecules and cells-nanoparticles. In this review we aim to exhibit
the state-of the art advances of the Biophotonics in the diagnostic and
therapeutic field, and the role of optical tweezers.
