A biodegradable drug delivery system (DDS) is one the most promising therapeutic strategies for cancer therapy. Here, we propose a unique concept of light activation of black phosphorus (BP) at hydrogel nanostructures for cancer therapy. A photosensitizer converts light into heat that softens and melts drug-loaded hydrogel-based nanostructures. Drug release rates can be accurately controlled by light intensity, exposure duration, BP concentration, and hydrogel composition. Owing to sufficiently deep penetration of near-infrared (NIR) light through tissues, our BP-based system shows high therapeutic efficacy for treatment of s.c. cancers. Importantly, our drug delivery system is completely harmless and degradable in vivo. Together, our work proposes a unique concept for precision cancer therapy by external light excitation to release cancer drugs. If these findings are successfully translated into the clinic, millions of patients with cancer will benefit from our work.

Black Phosphorus Quantum Dots

Due to the inherent limitations, single chemo or photothermal therapies (PTT) are always inefficient. The combination of chemotherapy and PTT for the treatment of cancers has attracted a great interest during the past few years. As a photothermal agent, black phosphorus quantum dots (BPQDs) possess an excellent extinction coefficient, high photothermal conversion efficacy, and good biocompatibility. Herein, we developed a photo- and pH-sensitive nanoparticle based on BPQDs for targeted chemo-photothermal therapy. Doxorubicin (DOX) was employed as a model drug. This nanosystem displayed outstanding photothermal performance both in vitro and in vivo. Folic acid conjugation onto the surface endowed this system an excellent tumor-targeting effect, which was demonstrated by the cellular targeting assay. The BPQDs-based drug delivery system exhibited pH- and photo-responsive release properties, which could reduce the potential damage to normal cells. The in vitro cell viability study showed a synergistic effect in suppressing cancer cell proliferation. Therefore, this BPQDs-based drug delivery system has substantial potential for future clinical applications.

Nano Drug Delivery

Nano drug delivery systems can control the ordered release of drugs. To achieve the target of supplying therapeutics and nutrients at the same time, a novel nano drug delivery system with a core–shell structure was prepared by coaxial electrospinning. Polyacrylonitrile (PAN) has been used to produce a drug release scaffold in the shell section, mixed with absorbable silk fibroin peptide (SFP) as a nutrient. Ciprofloxacin (CPFX), a broad-spectrum antibiotic, was used as the core, as well as an antibacterial agent. Owing to its low molecular weight, using a pure SFP thin solution to manufacture nanofibers by electrospinning is still technically challenging. Thus, different ratios of PAN to SFP were used in the shell electrospinning solution. In this research, a novel nano dual-functionality drug delivery system has been successfully prepared. In vitro testing demonstrated that nanofibers could supply more nutrients with increasing SFP in shell solutions; however, the ability to maintain controlled release was reduced. It was found that the nanofiber membrane had the best controlled drug release capability for a PAN-to-SFP mass ratio of 95:5. Overall, most ciprofloxacin was released in the first 12 h, while the release of SFP was constant throughout the first 24 h. Our modeling demonstrated that the release of CPFX and SFP is best described using a first-order kinetic model. The developed drug delivery system is designed to release antimicrobial drugs in a controlled manner and provide absorbable nutrients simultaneously.
