Proposed are a stabilizer for an adeno-associated virus (AAV) and a method for stabilizing an adeno-associated virus using the same. More particularly, the present disclosure relates to a stabilizer for an adeno-associated virus including a surfactant or albumin, an adeno-associated virus liquid formulation including adeno-associated virus the stabilizer, and a production method for an adeno-associated virus with improved stability. The technology, according to the present disclosure, inhibits excessive aggregation between viruses when producing a gene delivery virus and therapeutic nanoparticles using an adeno-associated virus and forming an additional polyphenol binder for this purpose, thereby maintaining the particle size to an effective size for drug delivery and improving the stability in the liquid phase. Therefore, the technology is expected to be very useful in the field of drug delivery technology for gene therapy.
