Aim: Several types of nanocarriers, most of which show significant cytotoxicity, have been developed to overcome the problem of gene-delivery barriers. Biocompatibility, low toxicity and water solubility of carbon nanodots (CNDs) are major advantages that recommend them as delivery systems. Materials & methods: We present a simple method to produce positively charged CNDs. Ethanolamine, ethylenediamine and hydrogen peroxide were utilized to synthesize these CNDs. Results & conclusion: Our results indicated that delivery of the CND–siGFP complex led to significant switching-off of the fluorescence of the GFP-expressing A549 cell. Next, the A549 cells were transfected with siRNA against BiP, which is a pivotal protein in the chemotherapy resistance of cancer cells. The expression levels of BiP decreased remarkably.

Host Polymer

It requires multistep synthesis and conjugation processes to incorporate multifunctionalities into a polyplex gene vehicle to overcome numerous hurdles during gene delivery. Here, we describe a supramolecular platform to precisely control, screen, and optimize molecular architectures of siRNA targeted delivery vehicles, which is based on rationally designed host-guest complexation between a β-cyclodextrin–based cationic host polymer and a library of guest polymers with various PEG shape and size, and various density of ligands. The host polymer is responsible to load/unload siRNA, while the guest polymer is responsible to shield the vehicles from nonspecific cellular uptake, to prolong their circulation time, and to target tumor cells. A series of precisely controlled molecular architectures through a simple assembly process allow for a rapid optimization of siRNA delivery vehicles in vitro and in vivo for therapeutic siRNA-Bcl2 delivery and tumor therapy, indicating the platform is a powerful screening tool for targeted gene delivery vehicles.
