Title:
FRAME STRUCTURE-BASED NANOPARTICLE USED FOR MASS CYTOMETRY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/005614
Kind Code:
A1
Abstract:
A frame structure-based nanoparticle used for mass cytometry and a preparation method therefor. The nanoparticle comprises metal ions, an antibody, and a coordination network framework formed by connecting organic ligands to each other by means of a linker, wherein the metal ions are bonded to the organic ligands; the linker is an organic linker having the functionality of n or a metal cluster having a coordination number of n, and n is greater than or equal to 2; and the antibody is connected to the organic ligands or the linker by means of a grafting agent. The nanoparticle can load a plurality of metal isotopes, the loading capacity is high, and a high-sensitivity metal detection signal having a plurality of available metal isotope channels can be provided in flow-type mass spectrometry detection, thereby achieving single-cell protein analysis and detection of simultaneous measurement of more cell parameters, and providing an important analysis tool for accurate diagnosis of diseases at the gene level and research and development detection of biomedicine.
