Applicazioni

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]

Azioni biochim/fisiol

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.

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.
