Alpha-fetoprotein (AFP) is a reliable clinical marker of hepatocellular carcinoma (HCC). A highly sensitive fluorometric aptamer nanoprobe is described for AFP detection. It is based on fluorescence resonance energy transfer (FRET) between AFP aptamer labelled with 5-carboxyfluorescein (FAM) and palladium nanoparticles (PdNPs). The PdNPs quench the green fluorescence of the FAM-AFP aptamer via interactions...
Two‐photon activated photodynamic therapy (TPA‐PDT) is a recently developed technique that shows a potential for medical application. In contrast to traditional one‐photon activated PDT, TPA‐PDT can increase the treatment depth and decrease the damage to healthy tissue by using a near‐infrared two‐photon laser. However, this technique also suffers from the fact that approved photosensitive drugs have...
