Seventy-nine liver specimens were analyzed after spectral calibration, noise-band removal, and normalization within 450–900 nm.

We observed obvious morphological changes, especially the early apoptotic phenomena, in both cancer cells.

The design and operating parameters confirmed the device's safety and energy efficiency. In vitro LED irradiation on fibroblasts increased cell viability, without inducing proliferation. The treatment prevented cellular shrinkage, as evidenced by a higher number of smaller cells in the control group. Irradiation also enhanced cell migration at 72 and 96 h after treatment. Significantly increased adhesion to fibronectin was observed in the irradiated group, with no effect on type I collagen adhesion.

Here, we employ Brillouin microspectroscopy, a non-invasive, label-free optical technique, to quantify the mechanical properties of human fibrotic tissue in in situ. We show that Brillouin spectroscopy distinguishes fibrotic tissue from healthy tissue on the basis of localized differences in the complex longitudinal modulus and enables real-time monitoring of dynamic alterations in viscoelastic properties during fibrogenesis. To our knowledge, this is the first demonstration of Brillouin spectroscopy for in situ characterization of fibrosis and wound healing in a human model.
