Chitosan (CS) has long been expected to be an ideal gene carrier for its high biosafety.[1] However, the low transfection efficiency of the raw chitosan-based vector has long been a problem troubling the researchers in medicine due to its poor water solubility, low electric charge density, dissociation problem, and other disadvantages.[2] In this work, CS with low molecular weight (MW) were...
