CD Bioparticles offers custom services to help you develop your upconversion nanoparticles lateral flow assays (LFA). We offer services ranging from custom nanoparticle conjugation to whole LFA optimization. The intensive studies of LFA focus on the improvements of signal labels to achieve ultrahigh sensitivity, superior quantitative ability and great robustness. Colorimetric signal labels remain the most investigated and wide applied, but the quantitative ability always remains the bottleneck of colorimetric LFA. Upconversion nanoparticles (UCNPs) are highly promising materials for LFA development due to their unique luminescent properties. UCNPs with superior characteristics of a large anti-Stokes shift, excellent luminescence brightness, non-photobleaching, high stability and SNR and long luminous lifetime can significantly improve the detection sensitivity in LFA. They have been applied in extensive range of detection, comprising metal ions, bacteria, disease biomarkers etc.
