This review article deals with the concepts, principles and applications of visible-light and
near-infrared (NIR) fluorescence and surface-enhanced Raman scattering (SERS) in in vitro …

The long-dreamed-of capability of monitoring the molecular machinery in living systems has
not been realized yet, mainly due to the technical limitations of current sensing technologies …

Ultrathin lensless fibre endoscopes offer minimally invasive investigation, but they mostly
operate as a rigid type due to the need for prior calibration of a fibre probe. Furthermore …

Fiber-based micro-endoscopes are a critically important tool for minimally-invasive deep-
tissue imaging. However, current micro-endoscopes cannot perform three-dimensional …

Multimode fibers can guide thousands of modes capable of delivering spatial information.
Unfortunately, mode dispersion and coupling have so far prevented their use in endoscopic …

UV light has been extensively employed in drug delivery because of its versatility, ease of
manipulation, and ability to induce chemical changes on the therapeutic carrier. Here we …

Flexible fiber-optic endoscopes provide a solution for imaging at depths beyond the reach of
conventional microscopes. Current endoscopes require focusing and/or scanning …

Optical fiber technology has significantly bolstered the growth of photonics applications in
basic life sciences research and in biomedical diagnosis, therapy, monitoring, and surgery …

Physical delivery of anticancer drugs in controlled anatomic locations can complement the
advances being made in chemo‐selective therapies. To this end, an optical fiber catheter is …

Endomicroscopy is an emerging imaging modality, that facilitates the acquisition of in vivo, in
situ optical biopsies, assisting diagnostic and potentially therapeutic interventions. While …
