Grid computing is a newly developed technology for complex systems with large-scale resource sharing and multi-institutional collaboration. The prominent feature of grid computing is the collaboration of multiple entities to perform collaborative tasks that rely on two fundamental functions: communication and resource sharing. Since the Internet is not… (More)
This study assessed the diversity and composition of bacterial communities in four different soils (human-, penguin-, seal-colony impacted soils and pristine soil) in the Fildes Region (King George Island, Antarctica) using 454 pyrosequencing with bacterial-specific primers targeting the 16S rRNA gene. Proteobacteria, Actinobacteria, Acidobacteria, and… (More)
We demonstrate a novel, rapid and label-free assay for the detection of Ag(+) and biothiols with high sensitivity and selectivity by utilization of Ag nanoparticle-decorated graphene quantum dots.
Herein, to mimic complex natural system, polyelectrolyte multilayer (PEM)-coated mesoporous silica nanoreactors were used to compartmentalize two different artificial enzymes. PEMs coated on the surface of mesoporous silica could serve as a permeable membrane to control the flow of molecules. When assembling hemin on the surface of mesoporous silica, the… (More)
The BSA-Cu3(PO4)2·3H2O hybrid nanoflower was used as a biomimetic catalyst with excellent catalytic activity, durability and stability. When GOx was used as the protein component, this composite could realize self-activated cascade catalysis. Our nanoflower system could also be used to decompose organic pollutants with high efficiency.
Herein, a non-enzymatic and label-free strategy based on DNA-fueled molecular machine was developed for ultrasensitive detection of telomerase activity in cancer cell extracts even at the single-cell level.
Developing methods of decreasing the harm to cell and increasing the antibacterial efficiency is becoming a potential topic of medical treatments. We demonstrated a hyaluronidase-triggered photothermal platform for killing bacteria based on silver nanoparticles (AgNPs) and graphene oxide (GO). The property of the hyaluronidase (HAase)-triggered release… (More)
Artificial light-harvesting systems have received great attention for use in photosynthetic and optoelectronic devices. Herein, a system involving G-quartet-based hierarchical nanofibers generated from the self-assembly of guanosine 5'-monophosphate (GMP) and a two-step Förster resonance energy transfer (FRET) is presented that mimics natural… (More)
Based on enzymatic reactions-triggered changes of pH values and biocomputing, a novel and multistage interconnection biological network with multiple easy-detectable signal outputs has been developed. Compared with traditional chemical computing, the enzyme-based biological system could overcome the interference between reactions or the incompatibility of… (More)
