A lateral flow test (LFT),[1] also known as a lateral flow device (LFD), lateral flow immunochromatographic assay, or rapid test, is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment. LFTs are widely used in medical diagnostics in the home, […]

Time-resolved fluorescence beads, as a special type of functional microspheres, are polystyrene microspheres internally embedded with complexes of rare earth ions. The rare earth ions commonly used for internal embedding include Eu3+, Tb3+, Sm3+, and Dy3+. When these rare earth ions form complexes with certain ligands such as β-diketones and aromatic amines, they can absorb
