Abstract

ABSTRACT Intranasal administration offers a rapid and non‐invasive route to deliver therapeutics directly from the nasal cavity into the brain for treating central nervous system (CNS) disorders. However, its efficacy is hampered by limited CNS targeting efficiency and rapid clearance in the nasal microenvironment. Here, a Ca 2+ responsive alginate hydrogel drug delivery system (namely SA@T SCC ) encapsulating a STING inhibitor within a neuronal targeting aptamer‐modified DNA nanocage for intranasal administration is developed. SA@T SCC demonstrates enhanced nasal retention, sustained release, and efficient transport of cargo into the CNS, leading to robust accumulation in the brain and spinal cord of…
