Three-dimensional bi-functional refractive index and fluorescence microscopy (BRIEF) [PDF]
arXiv, 2020 Fluorescence microscopy is a powerful tool for imaging biological samples with molecular specificity. In contrast, phase microscopy provides label-free measurement of the sample's refractive index (RI), which is an intrinsic optical property that quantitatively relates to cell morphology, mass, and stiffness.

High-resolution methods for fluorescence retrieval from space [PDF]
, 2010 The retrieval from space of a very weak fluorescence signal was studied in the O2A and O2B oxygen atmospheric absorption bands. The accuracy of the method was tested for the retrieval of the chlorophyll fluorescence and reflectance terms contributing to ...

Molecular Oncology, EarlyView.Cancer‐associated fibroblasts (CAFs) promote cancer growth, invasion (metastasis), and drug resistance. Here, we identified functional and diverse circulating CAFs (cCAFs) in patients with metastatic prostate cancer (mPCa). cCAFs were found in higher numbers and were functional and diverse in mPCa patients versus healthy individuals, suggesting their ...

Influence of DNA on Ag(I)-C-Phycocyanin complexes [PDF]
arXiv, 2008 The effects of DNA on the fluorescence of silver phycocyanin complexes were investigated. It was shown, that the fluorescence intensity of phycocyanin decreases, when silver ions are added but the following DNA addition gives rise to fluorescence buildup. Fluorescence spectroscopy provides insight of silver phycocyanin interactions.
