Alzheimer's disease (AD) is the most common form of dementia, characterized by formation extracellular senile plaques and neuronal loss caused amyloid β (Aβ) aggregates in brains AD patients. Conventional strategies failed to treat clinical trials, partly due poor solubility, low bioavailability ineffectiveness tested drugs cross blood-brain barrier (BBB). Moreover, a complex, multifactorial neurodegenerative disease; one-target may be insufficient prevent processes AD.

Nanoparticle drug delivery systems have proved anti-tumor effects; however, they are not widely used in tumor therapy due to insufficient ability target specific sites, multidrug resistance drugs, and the high toxicity of drugs. With development RNAi technology, nucleic acids been delivered sites replace or correct defective genes knock down genes. Also, synergistic therapeutic effects can be achieved for combined delivery, which is more effective overcoming cancer cells. These combination therapies achieve better than delivering chemotherapeutic drugs alone, so scope has also expanded three aspects: drug-drug, drug-gene, gene-gene. This review summarizes recent advances nanocarriers co-delivery agents, including i) characterization preparation nanocarriers, such as lipid-based polymer inorganic carriers; ii) advantages disadvantages approaches; iii) effectual cases that applied systems; iv) future perspectives design nanoparticle co-deliver agents.
