Chemotherapy of hepatocellular carcinoma (HCC) is facing drug resistance, which leads to unsatisfactory therapeutic effect. Thus, a combination therapy using multiple drugs may overcome this challenge. The current study aims to realize a synergistic chemotherapy of HCC by using a near-infrared light (NIR) responsive nanocarrier to co-deliver the chemotherapeutic drug Doxorubicin (DOX) and molecular targeting agent Sorafenib (SF). The nanocarrier, which could effectively load DOX in its aqueous core while SF and IR-780 in its lipid bilayer, is fabricated from a temperature-sensitive liposome (TSL) modified with PF127. An efficient SF and DOX co-loading was achieved, and meanwhile the effective photothermal conversion of IR-780 under NIR laser may cause a disassembly of the liposome structure which may trigger a rapid drug release in tumor site, greatly boosting the synergetic chemotherapeutic effect. The NIR laser-triggered drug release and the synergistic anti-tumor effect were evaluated both in cell and animal experiments, which revealed that the PF127-modified TSL is a potent nanoplatform to improve the HCC treatment through co-delivering a drug combination.

Antibiotic therapy is the gold standard for bacterial infections treatment. However, the rapid increase in multidrug-resistant (MDR) bacterial infections and its recent use for secondary bacterial infections in many COVID-19 patients has considerably weakened its treatment efficacy. These shortcomings motivated researchers to develop new antibacterial materials, such as nanoparticle-based antibacterial platform with the ability to increase the chances of killing MDR strains and prevent their drug resistance. Herein, we report a new black phosphorus (BP)-based non-damaging near-infrared light-responsive platform conjugated with ZnO and Au nanoparticles as a synergistic antibacterial agent against Staphylococcus aureus species. First, BP nanosheets containing Au nanoparticles were assembled in situ with the ZnO nanoparticles prepared by a low-temperature solution synthesis method. Subsequently, the antibacterial activities of the resulting Au–ZnO–BP nanocomposite against the non-resistant, methicillin-resistant, and erythromycin-resistant S. aureus species were determined, after its photothermal efficacy was assessed. The synthesized nanocomposite exhibited excellent anti-S. aureus activity and good photothermal characteristics. The non-resistant S. aureus species did not produce drug-resistant bacteria after the treatment of multiple consecutive passages under the pressure of the proposed nanoantibiotic, but rapidly developed resistance to erythromycin. This work clearly demonstrates the excellent photothermal antibacterial properties of Au–ZnO–BP nanocomposite against the MDR S. aureus species.
