Water-soluble biomolecular glass microneedle and preparation method thereof

A biomolecular glass microneedle, comprising a microneedle array and a substrate;

• wherein at least a part of the microneedle array consists of a biomolecular glass;
• the biomolecular glass consists of a biomolecule, an inducer, and a solvent in a trace amount;
• the biomolecule is an amino acid and a derivative and/or a peptide thereof;
• the solvent in the trace amount means that a content of the solvent in the biomolecular glass is 0.1 wt % to 5 wt %;
• the inducer is selected from the group consisting of a nucleotide, a nucleotide polymer, RNA, DNA, and/or a pH regulator;
• and the pH regulator is one or more selected from the group consisting of DL-tartaric acid, hydrochloric acid, sulfuric acid, phosphoric acid, lactic acid, lactobionic acid, citric acid, tartaric acid, oxalic acid, DL-malic acid, maleic acid, quinic acid, adipic acid, fumaric acid, hexanoic acid, heptanoic acid, caprylic acid, valeric acid, butyric acid, propionic acid, and glacial acetic acid.
