The Role of Hydrogen Peroxide and Peroxiredoxins throughout the Cell Cycle
Antioxidants, 2020 Hydrogen peroxide (H2O2) is an oxidizing agent that induces cellular damage at inappropriate concentrations and gives rise to an arrest during cell cycle progression, causing cell death.

Fluorescence Activated Cell Sorting
Definitions, 2020 1. Cell Preparation: The goal is to prepare a sample containing as many single cells as possible. Doublets or higher order clumps will either be detected or thrown out by the cytometer, or will confuse the instrument and result in sort mistakes ...

Use of nuclepore filters for counting bacteria by fluorescence microscopy
Applied and Environmental Microbiology, 1977 Polycarbonate Nuclepore filters are better than cellulose filters for the direct counting of bacteria because they have uniform pore size and a flat surface that retains all of the bacteria on top of the filter. Although cellulose filters also retain all

Fluorescence quenching in graphene: a fundamental ruler and evidence for transverse plasmons [PDF]
Phys. Rev. B 84, 165438 (2011), 2011 Graphene's fluorescence quenching is studied as a function of distance. Transverse decay channels, full retardation and graphene-field coupling to all orders are included, extending previous instantaneous results. For neutral graphene, a virtually exact analytical expression for the fluorescence yield is derived, valid for arbitrary distances and only ...
