Abstract:
Background: The Glassy Carbon Electrode (GCE) was modified with zinc oxide nanoparticles to enhance the electrocatalytic activity of the redox behavior of cefotaxime ion. ATOMIC Force Microscopy (AFM) photographic studies showed the nanorod like structure of the zinc oxide, which was coated uniformly on the electrode surface. Methods: The zinc oxide nanorod modified electrode was used as novel voltammetric determination of cefotaxime. The results of voltammetric behavior are satisfactory in the electro oxidation of cefotaxime, and exhibit considerable improvement compared to glassy carbon electrode. Results: Under the optimized experimental conditions, the ZnO nanorod modified electrode exhibit better linear dynamic range from 300 ppb to 700 ppb with lower limit of detection 200 ppb for the stripping voltammetric determination of cefotaxime. Conclusion: The pharmaceutical and clinical formulation of cefotaxime was successfully applied for accurate determination of trace amounts on ZnO nanomateials modified electrode.

Abstract:
This paper describes a method of catalyst-assisted pyrolysis of preceramic precursors for the synthesis of Si-based nanostructures. Through tuning the processing conditions, clustered SiOx amorphous nanowires, bundled single-crystalline Si3N4 nanowires, Y-shape and network-like branched single-crystalline Si3N4 nanostructures, aligned single-crystalline Si3N4 nanowires, and so on, have been synthesized. The results reveal that it is a simple and easy-controlling method, and has potential for mass production of nanomateirals of controlled morphology.

Abstract:
Lanthanide-doped semiconductors find usage in a wide variety of applications. In this work, Eu3+-doped rutile TiO2 nanocrystals have been successfully prepared at room temperature by a sonochemical method. The nanocrystalline sample has been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. A possible mechanism is proposed to explain the formation of Eu3+-doped TiO2 nanomateirals. Additionally, the characteristic emissions of Eu3+ can be found upon excitation in the region of TiO2 absorption, indicating that an energy transfer from TiO2 to Eu3+ occurs for the doped sample.

Abstract:
MgAl layered double hydroxides adsorbed anacardic acid (L-A complex) nanomateial used as a biological pesticide, could kill cutworms larvae (Spodoptera litura). This study assessed the effect of the MgAl layered double hydroxides, anacardic acid, and L-A complex on growth and development of sweet mustard trees, their toxicity on mice and the anacardic acid substance residues of L-A complex on sweet mustard trees (Brassica integrifolia) using HPLC method. The results showed that the MgAl layered double hydroxides and L-A complex did not affect the growth indexes including body height, root length, fresh weight, dry weight and chlorophyll concentrations of sweet mustard when killing larvae dose of 0,148 mg/mL was applied to the plants. The toxicity evaluation on mice indicated LD50 values of anacardic acid was 2378,41 mg/kg body weight, while no mice died from using L-A complex with anacardic acid concentration of 2553 mg/kg body weight. These results indicated that the toxicity of anacardic acid was reduced as using anacardic acid with MgAl layered double hydroxides in comparison with using anacardic acid alone. In testing the toxicity of free LDH, at dose applying on mice 6000 mg/kg body weight, no death mice or any abnormal behaviors of them was recorded. The result also showed that the anacardic acid residues in mustard leaves decreased from 40,6 mg/kg to 15,7 mg/kg leaves after 6 days. Therefore, all the results indicated that LDH, anacardic acid and L-A complex had no acute toxicity in mice and negative effect on growth and development of mustard plant. Prospectively, anacardic acid and L-A complex can be used as biological pesticides and safety materials in agriculture.

Abstract:
Abstract Background Despite tremendous progress has been achieved in tumor theranostic over the past decade, accurate identification and complete eradication of tumor cells remain a great challenge owing to the limitation of single imaging modality and therapeutic strategy. Results Herein, we successfully design and construct BiVO4/Fe3O4@polydopamine (PDA) superparticles (SPs) for computed tomography (CT)/photoacoustic (PA)/magnetic resonance (MR) multimodal imaging and radiotherapy (RT)/photothermal therapy (PTT) synergistic therapy toward oral epithelial carcinoma. On the one hand, BiVO4 NPs endow BiVO4/Fe3O4@PDA SPs with impressive X-ray absorption capability due to the high X-ray attenuation coefficient of Bi, which is beneficial for their utilization as radiosensitizers for CT imaging and RT. On the other hand, Fe3O4 NPs impart BiVO4/Fe3O4@PDA SPs with the superparamagnetic property as a T2-weighted contrast agent for MR imaging. Importantly, the aggregation of Fe3O4 NPs in SPs and the presence of PDA shell greatly improve the photothermal conversion capability of SPs, making BiVO4/Fe3O4@PDA SPs as an ideal photothermal transducer for PA imaging and PTT. By integrating advantages of various imaging modalities (CT/PA/MR) and therapeutic strategies (RT/PTT), our BiVO4/Fe3O4@PDA SPs exhibit the sensitive multimodal imaging feature and superior synergistic therapeutic efficacy on tumors. Conclusions Since there are many kinds of building blocks with unique properties appropriating for self-assembly, our work may largely enrich the library of nanomateirals for tumor diagnosis and treatment.

Abstract:
Abstract Background Recently, gadolinium-intercalated carbon dots (Gd@C-dots) have demonstrated potential advantages over traditional high-Z nanoparticles (HZNPs) as radiosensitizers due to their high stability, minimal metal leakage, and remarkable efficacy. Results In this work, two Gd@C-dots formulations were fabricated which bore carboxylic acid (CA-Gd@C-dots) or amino group (pPD-Gd@C-dots), respectively, on the carbon shell. While it is critical to develop innovative nanomateirals for cancer therapy, determining their tumor accumulation and retention is equally important. Therefore, in vivo positron emission tomography (PET) was performed, which found that 64Cu-labeled pPD-Gd@C-dots demonstrated significantly improved tumor retention (up to 48 h post injection) compared with CA-Gd@C-dots. Indeed, cell uptake of 64Cu-pPD-Gd@C-dots reached close to 60% of total dose compared with ~ 5% of 64Cu-CA-Gd@C-dots. pPD-Gd@C-dots was therefore further evaluated as a new radiosensitizer for non-small cell lung cancer treatment. While single dose radiation plus intratumorally injected pPD-Gd@C-dots did lead to improved tumor suppression, the inhibition effect was further improved with two doses of radiation. The persistent retention of pPD-Gd@C-dots in tumor region eliminates the need of reinjecting radiosensitizer for the second radiation. Conclusions PET offers a simple and straightforward way to study nanoparticle retention in vivo, and the selected pPD-Gd@C-dots hold great potential as an effective radiosensitizer. Graphic abstract
