SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement
Advanced Functional Materials, EarlyView.An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...

Fluorescence microscope light source stability
Histochemistry and Cell Biology, 2019The process of fluorescence starts with the efficient generation of light that is required for the excitation of fluorophores. As such, light sources are a crucial component of a fluorescence microscope. Choosing the right illumination tool can not only improve the quality of experimental results, but also the microscope's economic and environmental ...

Study of microscopic porphyrin fluorescence
Urology, 1987A technique of porphyrin (hematoporphyrin derivative [Hpd]) fluorescence microscopy was evaluated by studying Hpd uptake, retention, and loss in established human cancer cell lines. Hpd uptake appeared to be qualitatively identical in the three cell lines used, but the rate of loss was slowest in the renal-carcinoma-derived line, suggesting a cellular ...

Microscopic fluorescence in photodynamic therapy
The Laryngoscope, 1986AbstractThe use of hematoporphyrin derivative (HPD) as a photosensitizer has been studied in malignant tumor detection via fluorescence and in tumor destruction via a toxic photochemical reaction. Squamous cell carcinoma has been induced in hamster buccal mucosa utilizing the known carcinogen dimethyl‐benzanthracene. HPD was injected intraperitoneally,

Laser Scanning Fluorescence Microscope
SPIE Proceedings, 1988We report on the development of a laser scanning fluorescence microscope possessing several features which facilitate its application to biological and biophysical analyses in living cells. It is built around a standard inverted microscope stand, enabling the use of standard optics, micromanipulation apparatus, and conventional (including video ...

Vidicon Microscope for Counting Fluorescent Particles
Review of Scientific Instruments, 1971Weakly fluorescent particles may be counted or displayed through use of the light integrating property of vidicons. This paper describes a fluorescence microscope-vidicon system designed for counting bacteria. It employs incident bright-field uv illumination with an inexpensive television (TV) system.

Fluorescence in the tandem scanning microscope
Journal of Microscopy, 1990SUMMARYOur studies have shown that the fluorescence mode can be used to good effect in both tandem scanning microscopes (TSM: direct view confocal microscopes) as well as confocal scanning laser microscopes (CSLM). Applications are presented which show that the two great advantages of TSM are real‐time viewing and real colour, which allow faster use ...
