As an anti-Stokes shifting materials, upconversion nanoparticles (UCNPs) are the most efficient materials for converting near infrared (NIR) light to UV and visible light. UCNPs has advantages, including large anti-Stokes shifts for considerable separation of the upconversion luminescence (UCL) from the excitation, narrow emission bandwidths for easily multiplex imaging, improved signal-to-noise ratio. Since these characteristics, UCNPs have been employed in many fields of biological science such as cells and tissues labeling for bio-imaging, bio-detection and multiplexed analysis. In this study, UCNPs with various colors were synthesized by controlling feed composition. Their physicochemical and photoluminescence properties were investigated. The surface modification of UCNPs for biosensing was also conducted. |
