Synonyms: HOSu; 1-Hydroxy-2,5-pyrrolidinedione
N-Hydroxysuccinimide (HOSu; 1-Hydroxy-2,5-pyrrolidinedione) is a covalent crosslinker commonly used in bioconjugation technology with a primary amine group. N-Hydroxysuccinimide reacts with amino groups (-NH2) to form a stable amide bond, which can modify amino-containing biomolecules. N-Hydroxysuccinimide can be used, for example, for protein labeling with fluorescent dyes and enzymes, surface activation of chromatography supports, microbeads, nanoparticles and microarray slides, and chemical synthesis of peptides. N-Hydroxysuccinimide has a wide range of applications in biomaterial synthesis (such as collagen, chitosan crosslinking), drug delivery systems (such as hydrogel preparation) and tissue engineering .

5β-Cholanic acid is a hydrophobic modifier used to modify polymer carriers. 5β-Cholanic acid can improve the acid stability, cell penetration efficiency and drug sustained release ability of nanocarriers, and optimize the oral effectiveness of delivered molecules. 5β-Cholanic acid can covalently bind to Glycol chitosan (GC) to form a GC-CA conjugate, which optimizes the hydrophobic anchoring ability of nanoparticles and enables them to be stably adsorbed on the surface of PLGA nanoparticles. Such nanoparticles can resist dissociation in the gastric acid environment and maintain positive charge to enhance endocytic uptake by intestinal epithelial cells (such as Caco-2 cells). 5β-Cholanic acid can be used in the development of drug delivery systems .

Di-tert-butyl dicarbonate (tBOC) is a covalent modification agent for hydroxyl groups (-OH) on the chitosan molecular chain. Di-tert-butyl dicarbonate selectively modifies chitosan and stabilizes the material structure through hydrophobic encapsulation. Di-tert-butyl dicarbonate reacts with the -OH groups of chitosan to form a hydrophobic layer, and in conjunction with triethylamine (TEA), removes trifluoroacetic acid (TFA) salts produced during the electrospinning process, preserving the nanofiber structure and high porosity of the membrane, and improving the material's cytocompatibility and mineralization-promoting ability. Di-tert-butyl dicarbonate can be used in research in the field of guided bone regeneration (GBR) .
