Nonarginine (D-R9) has been reported to be one of the most efficacious protein transduction domains (PTDs) for the intracellular cargo delivery such as DNA, RNA, proteins, and particles. Although oligoarginines are capable of forming polyplex with DNA by electrostatic interaction, the length of oligoarginine can affect the toxicity and gene expression. The reducible poly(oligo-D-arginine) (rPOA) composed of the Cys-(D-R9)-Cys repeating unit forming disulfide bonds between terminal cysteinyl-thio

Advancements in micro-resolution 3D printers have significantly facilitated the development of highly complex mass-producible drug delivery platforms. Conventionally, due to the limitations of micro-milling machineries, dissolvable microneedles (MNs) are mainly fabricated in cone-shaped geometry with limited drug delivery accuracy. Herein, to overcome the limitations of conventional MNs, a novel projection micro-stereolithography 3D printer-based self-locking MN for precise skin insertion, adhes

A wide variety of drug delivery systems have been developed for the delivery of anticancer agents. One of the most frequently used natural biomaterials in drug delivery systems is polysaccharides; however, they are difficult to digest and to eliminate from the body after systemic administration due to their high molecular weight natures and the absence of degrading enzymes. Therefore, the development of degradable and eliminable natural biomaterials is critical for successful in vivo application
