The study of alveolar macrophages (AM) from smokers by flow cytometry (FCM) has been limited by strong autofluorescence and the lack of reliable markers to identify macrophages. Crystal violet quenching was reported to be effective in reducing autofluorescence of AM. CD68 is a marker for macrophages in immunohistochemistry, but has been less useful in FCM because of poor surface expression. Thi...

Abstract Crystal Violet dye is a toxic organic pigment that has little solubility in water and causes serious health problems environmental pollution. In the current study, compound composed of multi-walled carbon nanotubes with chitosan was used. Experiments were conducted to adsorb crystal violet for both effect surface weight adsorbent contact time. Dye CS-OMWCNTs. And study pH ionic intensi...

A sensitive and selective amperometric sensing platform for lead (Pb(2+)) was developed based on a Pb(2+)-induced G-rich DNA conformational switch from a random-coil to G-quadruplex (G4) with crystal violet as the G4-binding indicator.

The first application of crystal violet as a selective fluorescent switch-on probe for i-motif DNA has been reported. This interaction has been exploited to develop a label-free DNA-based "OR" logic gate for potassium and hydrogen ions.
