Nitric oxide(NO) gas therapy has been regarded as a promising strategy for cancer treatment. However,its therapeutic efficiency is still unsatisfying due to the limitations of monotherapy. Previous preclinical and clinical studies have shown that combination therapy could significantly enhance therapeutic efficiency. Herein, a graphene oxide(GO)-L-arginine(L-Arg, a natural NO donor) hybrid nanogenerator is developed followed by surface functionalization of soybean lecithin(SL) for synergistic enhancement of cancer treatment through photothermal and gas therapy. The resultant GO-Arg-SL nanogenerator not only exhibited good biocompatibility and excellent endocytosis ability, but also exhibited excellent photothermal conversion capability and high sensitivity to release NO within tumor microenvironment via inducible NO synthase(i NOS) catalyzation. Moreover, the produced hyperthermia and intracellular NO could synergistically kill cancer cells both in vitro and in vivo. More importantly, this nanogenerator can efficiently eliminate tumor while inhibiting the tumor recurrence because of the immunogenic cell death(ICD) elicited by NIR laser-triggered hyperthermia and the immune response activation by massive NO generation. We envision that the GO-Arg-SL nanogenerator could provide a potential strategy for synergistic photothermal and gas therapy.

Plasma electrolytic liquefaction of cellulosic biomass

Plasma Science and Technology 2018年第4期20卷 8-16页

作者：汤丁亮张先徽杨思泽 College of Chemistry and chemical engineering Xiamen University fujian provincial key laboratory of Plasma and Magnetic Resonance Institute of Electromagnetics and Acoustics Department of Electronic Science College of Physical Science and Technology Xiamen University

In this paper, the rapid liquefaction of a corncob was achieved by plasma electrolysis, providing a new method for cellulosic biomass liquefaction. The liquefaction rate of the corncob was 95% after 5 min with polyethylene glycol and glycerol as the liquefying agent. The experiments not only showed that H~+ ions catalyzed the liquefaction of the corncob, but also that using accelerated H~+ ions, which were accelerated by an electric field, could effectively improve the liquefaction efficiency. There was an obvious discharge phenomenon, in which the generated radicals efficiently heated the solution and liquefied the biomass, in the process of plasma electrolytic liquefaction. Finally, the optimum parameters of the corncob liquefaction were obtained by experimentation, and the liquefaction products were analyzed.
