Cancer has been one among the main threats to the lives of citizenry for hundreds of years. Traditional drug therapy has certain defects such as poor targeting, easy degradation, high side effects, etc. Therefore, to enhance the treatment efficiency of anticancer agents, there is need of developing new drug delivery systems. Black phosphorus is a member of the 2D family, and it possess the potential to construct drug delivery system by virtue of its photothermal therapy, photodynamic therapy, and biodegradable properties. Due to their special structure BP are considered to be the best platform for drug delivery. They have shown large potential as near-infrared photothermal therapy agents and drug delivery for cancer therapy. The present review covered advances in BP- based drug delivery system along with its advantages and applications in cancer therapy.

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.

Abstract Background: Owing to the tunability of longitudinal surface plasmon resonance (LSPR), ease of synthesizing small size and excellent stability, AuNRs have been developed as photothermal agents for cancer therapy. However, PTT alone could not kill cancer cells completely due to the local heterogeneous distribution of heat in tumors, penetration depth of light, light scattering and absorption. In addition, the treatment systems based on AuNRs hold disadvantages of loading one antitumor drug or a low therapeutic efficiency. Therefore, the construction of the AuNRs theranostic system to achieve imaging-guided dual drug delivery and enhanced photothermal therapy for tumor still remains a great challenge.Methods: The AuNRs were prepared using a seedless method. A mesoporous silica shell layer was coated on the surface of the AuNRs by sol-gel method. Double anticancer drugs, DOX and Btz, were loaded into the AuNRs@MSN nanoparticles through physical absorption and covalent conjugation, respectively.Results: The release of DOX and Btz is found pH/thermal dual responsive in vitro. Compared with AuNRs@MSN, PDA-AuNRs@MSN exhibits an increased near-infrared (NIR) absorption at 808 nm and an enhanced photothermal effect. In contrast to chemotherapy or photothermal therapy alone, the integrated D/B-PDA-AuNRs@MSN nanoparticles show higher cell apoptosis and enhanced tumor treatment efficacy in vitro and in vivo.Conclusions: In this study, we designed a double-drug loading, enhanced chemo/photothermal therapy and pH/thermal responsive drug delivery system for photoacoustic (PA) imaging-guided tumor therapy. We believe that the multifunctional D/B-PDA-AuNRs@MSN theranostic probe could serve as an effective probe for the treatment of cancers.

Abstract Background Osteosarcoma (OS) is the most common primary malignant bone tumor occurring in children and young adults. Drug-resistant osteosarcoma often results in chemotherapy failure. Therefore, new treatments aimed at novel therapeutic targets are urgently needed for the treatment of drug-resistant osteosarcoma. Mitochondria-targeted phototherapy, i.e., synergistic photodynamic/photothermal therapy, has emerged as a highly promising strategy for treating drug-resistant tumors. This study proposed a new nano-drug delivery system based on near-infrared imaging and multifunctional graphene, which can target mitochondria and show synergistic phototherapy, with preferential accumulation in tumors. Methods and results Based on our previous study, (4-carboxybutyl) triphenyl phosphonium bromide (TPP), a mitochondria-targeting ligand, was conjugated to indocyanine green (ICG)-loaded, polyethylenimine-modified PEGylated nanographene oxide sheets (TPP-PPG@ICG) to promote mitochondrial accumulation after cellular internalization. Thereafter, exposure to a single dose of near-infrared irradiation enabled synergistic photodynamic and photothermal therapy, which simultaneously inhibited adenosine triphosphate synthesis and mitochondrial function. Induction of intrinsic apoptosis assisted in surmounting drug resistance and caused tumor cell death. After fluorescence imaging-guided synergistic phototherapy, the mitochondria-targeting, multifunctional graphene-based, drug-delivery system showed highly selective anticancer efficiency in vitro and in vivo, resulting in marked inhibition of tumor progression without noticeable toxicity in mice bearing doxorubicin-resistant MG63 tumor cells. Conclusion The mitochondria-targeting TPP-PPG@ICG nanocomposite constitutes a new class of nanomedicine for fluorescence imaging-guided synergistic phototherapy and shows promise for treating drug-resistant osteosarcoma.
