Imaging nanoprobes are a group of nanosized agents developed for providing improved contrast for bioimaging. Among various imaging probes, optical sensors capable of following biological events or progresses at the cellular and molecular levels are actually actively developed for early detection, accurate diagnosis, and monitoring of the treatment of diseases. The optical activities of nanoprob...

As a prospective material for biosensing, drug administration, and bioimaging, carbon dots (C-dots) have grown in popularity due to their outstanding visual characteristics, great biocompatibility, low cytotoxicity. result, there has been lot of curiosity about the development, potential applications CDOTs. Based on variations precursors methods preparation, CDOTs were divided into two classes....

Here, we report a straightforward synthesis process to produce colloidal Eu(3+)-activated nanophosphors (NPs) for use as bioimaging probes. In this procedure, poly(ethylene glycol) serves as a high-boiling point solvent allowing for nanoscale particle formation as well as a convenient medium for solvent exchange and subsequent surface modification. The La(OH)3:Eu(3+) NPs produced by this proces...

Near-infrared (NIR)-to-Visible upconversion fluorescent nanoparticles emit visible light upon NIR-light excitation, and are well suited for bioimaging, compared to the commonly used downconversionfluorescentmaterials.Thesenanoparticleshave advantages such as minimum photodamage to living organisms, weak background fluorescence, high detection sensitivity, and high light-penetration depth in tis...
