Application

Latex beads, amine-modified polystyrene, fluorescent orange has been used in functionalized microbeads for rapid antimicrobial susceptibility testing (AST) evaluation.[1][2] It has also been used in microparticle functionalization for the detection of live bacteria.[3]

Biochem/physiol Actions

Amine-modified polystyrene latex beads have been used to develop an electrochemical nitrite nanosensor as well as to validate a pharyngeal aspiration technique for exposing the mouse lung to respirable particles.

Recent studies have demonstrated that the mouse lung can be exposed to soluble antigens by aspiration of these antigens from the pharynx. This simple technique avoids the trauma associated with intratracheal instillation. In this study, the pharyngeal aspiration technique was

Rapid detection of bacteria and their susceptibility to specific antibiotics plays a vital role in microbial infection treatments. Antimicrobial susceptibility testing (AST) is a common measure to select effective drugs. However, the conventional practices, such as broth dilution, E-test, and

Questions

  1. The specified output emission is 540nm, which is green. However, the beads are labelled "yellow to orange". When exciting with green I detect fluorescence at 600nm on my spectrometer, which is yellow to orange. Is 540 the actual expected emission? or 600?

    1 answer
    1. The excitation range for this product is 470 nm to 525 nm, and the emission range is 535 nm to 650 nm.
