Solid-state nanopores have emerged as one of the most versatile tools for single-biomolecule detection and characterization. Nanopore sensing is based on the measurement of variations in ionic current as charged biomolecules immersed in an electrolyte translocate through nanometer-sized channels, in response to an external voltage applied across th...

Recently, bulk MoS2 crystals stacked by 1T'-MoS2 monolayers have been synthesized successfully, but little is known about their stacking sequences and topological properties. Based on first-principles calculations and symmetry-based indicator theory, we discovered that three predicted bulk structures of MoS2 (named 2M-, 1T'- and β-MoS2) stacked by ...

We report a novel s-tetrazine based covalent organic framework (TZA-COF) and its hybrid nanocomposites with reduced graphene oxide (TZA-COF-rGO) and Co metal to illustrate novel structure-activity relationships in this class of compounds for electrocatalytic oxygen reduction reaction (ORR). The Co-impregnated hybrid composites (TZA-COF-rGO-Co) were...

Surface nanobubbles are gaseous domains found at immersed substrates, whose remarkable persistence is still not fully understood. Recently, it has been observed that the formation of nanobubbles is often associated with a local high gas oversaturation at the liquid-solid interface. Tan, An and Ohl have postulated the existence of an effective poten...

Metalloproteins play important roles in a wide range of biological processes. The folding process of metalloproteins is complex due to the synergistic effects of the folding of their polypeptide chains and the incorporation of metal cofactors. The folding mechanism of the simplest iron-sulfur protein rubredoxin, which contains one ferric ion coordi...

Oral route is one of the most important portals of nanoparticle entry to the body. However, in vivo protein corona formed in the gastrointestinal tract has not been studied owing to the difficulty for the recovery of nanoparticles from the in vivo environment. In this study, by using the magnetic property of iron oxide nanoparticles (Fe3O4 NPs) and...

The function of an organic solar cell relies on making a contact surface between a donor and acceptor material. For efficient conversion of solar energy, this heterojunction must be maximized. Nanoparticulate systems already have a large surface-to-volume ratio per se. We increase the area of the heterojunction even further. Based on the miniemulsi...

Hierarchical nitrogen-doped carbon encapsulated hollow ZnSe/CoSe2 (ZnSe/CoSe2@N-C) nanospheres are fabricated by a convenient solvothermal and selenization approach, followed by a carbonization process. The as-obtained ZnSe/CoSe2@N-C possesses a multilevel nanoscale architecture composed of a thin carbon shell with a size of around 12 nm and hollow...

Circulating tumor cells (CTCs) acquire mesenchymal markers (e.g., N-cadherin) and lose epithelial markers (e.g., epithelial cell adhesion molecule, EpCAM) during the epithelial-mesenchymal transition (EMT) and are therefore ideal biomarkers of tumor metastasis. However, it is still a challenge to efficiently capture and detect circulating tumor cel...
