Gold nanoparticles have unique optical properties, such as surface plasmon resonance, resonance light scattering, easy surface modification, and good biocompatibility. The combination of peptides coupled to the surface of gold nanoparticles has many potential applications in chemistry, biology, and medicine. Polypeptide was coupled to the surface of gold nanoparticles and activated by 1- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS) reaction is the most commonly used coupling method. Generally, a two-step activation reaction is required: first, alkanoic acid containing mercapto groups is assembled on the surface of gold nanoparticles through gold-sulfur bonds to form a monomolecular layer. Then, the carboxyl group is activated by EDC-NHS, dehydrated and condensed with the amino group of polypeptide or protein, and finally forms amide bond.


Peptide and gold nanoparticle conjugates have been used in the study of immune recognition, transcription factors, mimic enzymes and protein inhibitors in biological simulation systems. A novel layer-by-layer coupling assembly system based on gold nanoparticles was designed. The assembly system combines fluorescence imaging, efficient cell entry, mitochondrial targeted transport and other functions, and has the characteristics of low toxicity and high stability. It is suitable for carrying drugs related to mitochondrial diseases or functional polypeptides that need to function through mitochondria.
