    Abstract: Disclosed are a nucleic acid functionalized metal nanoprobe and a preparation method therefor; according to the probe, metal cations with desirable biocompatibility are mixed with exogenous deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules to generate a DNA or RNA composite nanostructure; co-incubating is performed with a pathogenic microorganism, the composite nanostructure enters pathogenic microorganism cells through electrostatic adsorption, and unique microenvironment of high-level oxidizing and reducing substances possessed by the pathogenic microorganism is used to promote in-situ synthesis of the intelligent biological probe; accurate targeted labeling and real-time rapid detection of the pathogenic microorganism are achieved, and the probe is used for targeted intervention of infectious diseases such as lung infection, intestinal infection and influenza; combined with physical interventions such as photoelectricity, magnetocaloric effect, near infrared, multi-modal real-time dynamic and high-specificity rapid and accurate tracing and accurate killing of related lesions can be achieved.

    Abstract: Disclosed herein are second near-infrared (NIR-II) fluorescent composite and its production method. The method mainly includes the steps of, mixing a gold nanocluster having a plurality of a thiol-based compound on its outer surface and alpha-glycerylphosphorylcholine (alpha-GPC) in a solvent to form a mixture; replacing the solvent with an inert gas; and heating the mixture at a temperature about 100-200° C. in the presence of the inert gas until at least a portion of the gold nanocluster is encapsulated by a capping layer consisting of alpha-GPC, thereby producing the NIR-II fluorescent composite. The thus-produced NIR-II fluorescent composite is characterized by having an emission wavelength covering NIR-II region detectable by specialized camera. Also encompassed in the present disclosure is a method for conducting in vivo bioimaging of a target area in a subject. The method includes administering the present NIR-II fluorescent composite to the target area; and detecting the fluorescence emitted therefrom at a wavelength between 900 to 1700 nm.
