Detection and characterization of colorectal cancer by autofluorescence lifetime imaging on surgical specimens

Scientific Reports
Colorectal cancer (CRC) ranks among the most prevalent malignancies worldwide, driving a quest for comprehensive characterization methods. We report a characterization of the ex vivo autofluorescence lifetime fingerprint of colorectal tissues obtained ...

Autofluorescence of bone tissues [PDF]

Journal of Clinical Pathology, 1967
The phenomenen of autofluorescence of bone is due primarily to the collagen itself rather than to incidental substances adsorbed on to it. Fluorescent microscopy is a convenient method of dating the different microanatomical components of bone, and in this respect the same conclusions can be reached from the study of microradiographs or autofluorescent

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

FEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...
