The invention discloses a nano compound (RAP (at) KTP (at) AuNPs) for delivering rapamycin based on targeted peptide modified gold nanoparticles as well as a preparation method and application of the nano compound. In the nano compound, the surfaces of the gold nanoparticles are modified by polyethylene glycol to form a PEG layer; the K3 targeting peptide is connected to the surface of the PEG layer through non-covalent coupling; rapamycin is loaded and wrapped in the PEG layer. SH-PEG-SH is added into the AuNPs solution, and a PEG modified AuNPs solution is obtained through a reaction; diluting the K3 targeting peptide with pure water to obtain a diluted solution, adding the diluted solution into the PEG-modified AuNPs solution, and reacting to obtain a KTP-coated AuNPs solution; the preparation method comprises the following steps: dissolving rapamycin powder by using dimethyl sulfoxide, adding the rapamycin powder into a KTP (at) AuNPs solution, and reacting to obtain the nano-composite RAP (at) KTP (at) AuNPs. The nanocomposite provided by the invention can realize efficient and accurate delivery of rapamycin, and improves the effect of treating renal fibrosis.

Provided is a kit for detecting a glycoprotein contained in a sample using an optical condensation system, the kit comprising microparticles modified by host molecules and a dilution solution for diluting the sample, in which each of the host molecules binds specifically to the glycoprotein, the dilution solution comprises a blocking agent and a buffering agent, the pH value of the dilution solution is higher than the isoelectric point of the glycoprotein, the concentration of the blocking agent is lower than a concentration at which the non-specific adsorption between the host molecules is inhibited in an environment where a light-induced force does not act on the host molecules, and the salt concentration in the dilution solution is a concentration at which the microparticles modified by the host molecules cannot be precipitated by salting out.
