论文题目:Construction of an autonomously concatenated hybridization chain reaction for signal amplification and intracellular imaging

论文作者:Jie Wei, Xue Gong, Qing Wang, Min Pan, Xiaoqing Liu, Jing Liu, Fan Xia, Fuan Wang

发表日期:23 October 2017

论文摘要:Biomolecular self-assembly has spurred substantial research efforts for the development of low-cost point-of-care diagnostics. Herein, we introduce an isothermal enzyme-free concatenated hybridization chain reaction (C-HCR), in which the output of the upstream hybridization chain reaction (HCR-1) layer acts as an intermediate input to activate the downstream hybridization chain reaction (HCR-2) layer. The initiator motivates HCR-1 through the autonomous cross-opening of two functional DNA hairpins, yielding polymeric dsDNA nanowires composed of numerous tandem triggers T as output of the primary sensing event. The reconstituted amplicon T then initiates HCR-2 and transduces the analyte recognition into an amplified readout, originating from the synergistic effect between HCR-1 and HCR-2 layers. Native gel electrophoresis, atom force microscopy (AFM) and fluorescence spectra revealed that C-HCR mediated the formation of frond-like branched dsDNA nanowires and the generation of an amplified FRET signal. As a versatile and robust amplification strategy, the unpreceded C-HCR can discriminate DNA analyte from its mutants with high accuracy and specificity. By incorporating an auxiliary sensing module, the integrated C-HCR amplifier was further adapted for highly sensitive and selective detection of microRNA (miRNA), as a result of the hierarchical and sequential hybridization chain reactions, in human serum and even living cells through an easy-to-integrate “plug-and-play” procedure. In addition, the C-HCR amplifier was successfully implemented for intracellular miRNA imaging by acquiring an accurate and precise signal localization inside living cells, which was especially suitable for the ex situ and in situ amplified detection of trace amounts of analyte. The C-HCR amplification provides a comprehensive and smart toolbox for highly sensitive detection of various biomarkers and thus should hold great promise in clinical diagnosis and assessment. The infinite layer of multilayered C-HCR is anticipated to further strengthen the amplification capacity and reliability (anti-invasion performance) of intracellular imaging approach, which is of great significance for its bioanalytical applications.


论文题目:Bacterial species-identifiable magnetic nanosystems for early sepsis diagnosis and extracorporeal photodynamic blood disinfection

论文作者:Jianhao Wang, Hao Wu, Yanmei Yang, Rong Yan, Yuan Zhao, Yanhao Wang, Aihong Chen, Shilong Shao, Pengju Jiang, Yong-Qiang Li

发表日期: 26 October 2017

论文摘要:Despite the numerous bacteria detection and elimination techniques available nowadays, sensitive diagnosis and treatment of sepsis (caused by the presence of bacteria in the bloodstream), especially at the early stage, remain big challenges. Here we report a nanosystem for early sepsis diagnosis and complete extracorporeal blood disinfection, based on iron oxide magnetic nanoparticles functionalized with chlorin e6 molecules and bacterial species-identifiable aptamers (Fe3O4-Ce6-Apt). We demonstrate that the Fe3O4-Ce6-Apt nanosystem can achieve simultaneous blood bacterial species identification and enrichment in a single step, and the enriched bacteria can be easily detected with the assistance of fluorescence microscopic determination. Based on this Fe3O4-Ce6-Apt nanosystem, successful diagnosis of sepsis caused by a single (Staphylococcus aureus) or multiple species (Staphylococcus aureus and Escherichia coli) of bacteria in mice has been realized. Compared to the gold standard blood culture method, this Fe3O4-Ce6-Apt nanosystem-based strategy has a comparable detection sensitivity (around 10 colony-forming units) but a significantly shortened diagnosis turnaround time (within 1.5 h), revealing its great potential for early sepsis diagnosis in clinical settings. Moreover, benefitting from the strong photodynamic effect of the Fe3O4-Ce6-Apt nanosystem, complete extracorporeal blood disinfection has been achieved. Remarkably, we also demonstrate that the disinfected blood can be reused for mice transfusion application without inducing adverse reactions, indicating the fruitful potential of the Fe3O4-Ce6-Apt nanosystem for sepsis treatment. Apart from the sepsis-associated applications, we believe that the Fe3O4-Ce6-Apt nanosystem could find wide applications in the fields of health and environmental sciences that require bacteria monitoring and sterilization.

论文题目:MicroRNA detection by an amplification-free biosensor based on controllable solid-state electrochemiluminescence quenched by charge transfer

论文作者:Chang Liu, Lin Wang, Liping Lu, Tianfang Kang

发表日期:22 September 2017

论文摘要:Effective and sensitive microRNA detection is a great challenge. Most microRNA assays use an amplification strategy to obtain high sensitivity, which makes them complicated. Herein, we present a simple and amplification-free solid-state electrochemiluminescence (ECL) biosensor for the detection of miRNA based on high effective quenching by ferrocene and using N-butyldiethanolamine (BDEA) as a more effective co-reactant. Initially, the mixture of Nafion and Au nanoparticles (AuNPs) was cast onto the glassy carbon electrode (GCE) to form a Nafion–AuNPs film. The resulting electrode was then immersed into a solution of Ru(bpy)32+, where the solid-state Nafion–AuNPs/Ru(bpy)32+ could be obtained via electrostatic adsorption. The DNA molecular beacon, which was modified with thiol at one distal and the other was labeled with ferrocene (i.e., Fc-MB), was covalently attached to AuNPs on the ECL film through a Au–S bond. Afterwards, the remaining active sites of nonspecific adsorption were blocked with 6-mercapto-1-hexanol (MCH). When the target miRNA was present, it hybridized with the complementary part in the loop of Fc-MB and formed a double-stranded structure. This conformational change led the quencher away from the electrode, resulting in a remarkable increase in ECL intensity. Under the optimum condition, the ECL signal had a linear relationship with miRNA concentration ranging from 0.01 pM to 1 × 103 pM, with a limit of detection of 10 fM. Moreover, our biosensor showed remarkable specificity, outstanding reproducibility, good stability and excellent performance in real sample investigation with no amplification. Therefore, this developed strategy has great potential in early miRNA-related cancer diagnosis.

论文题目:Computational approaches to cell–nanomaterial interactions: keeping balance between therapeutic efficiency and cytotoxicity

论文作者:Hong-ming Ding, Yu-qiang Ma

发表日期:03 October 2017

论文摘要:Owing to their unique properties, nanomaterials have been widely used in biomedicine since they have obvious inherent advantages over traditional ones. However, nanomaterials may also cause dysfunction in proteins, genes and cells, resulting in cytotoxic and genotoxic responses. Recently, more and more attention has been paid to these potential toxicities of nanomaterials, especially to the risks of nanomaterials to human health and safety. Therefore, when using nanomaterials for biomedical applications, it is of great importance to keep the balance between therapeutic efficiency and cytotoxicity (i.e., increase the therapeutic efficiency as well as decrease the potential toxicity). This requires a deeper understanding of the interactions between various types of nanomaterials and biological systems at the nano/bio interface. In this review, from the point of view of theoretical researchers, we will present the current status regarding the physical mechanism of cytotoxicity caused by nanomaterials, mainly based on recent simulation results. In addition, the strategies for minimizing the nanotoxicity naturally and artificially will also be discussed in detail. Furthermore, we should notice that toxicity is not always bad for clinical use since causing the death of specific cells is the main way of treating disease. Enhancing the targeting ability of nanomaterials to diseased cells and minimizing their side effects on normal cells will always be hugely challenging issues in nanomedicine. By combining the latest computational studies with some experimental verifications, we will provide special insights into recent advances regarding these problems, especially for the design of novel environment-responsive nanomaterials.

论文作者:Yun-Feng Zen, Zi-Cheng Fu, Fei Liang, Yong Xu, Dan-Dan Yang, Zhi Yang, Xin Gan, Zhe-Shuai Lin, Yong Chen, Wen-Fu Fu

发表日期:30 October 2017

论文摘要:Selective hydrogenation of nitrile groups to primary amines is challenging owing to their high reactivity towards producing secondary and tertiary amines. An unprecedented and efficient system for the hydrogenation of nitrile and nitro groups to primary amines catalyzed by Ni2P nanoparticles in mixed aqueous H3NBH3 solution under ambient conditions is reported. The system exhibits high catalytic selectivity towards generating primary amines, resulting in good isolated yields. Density functional theory calculations rationalize the observed results that composite interactions among species on the catalyst surface alter the catalytic pathway.
