Infected Tissue Regeneration In article number 2205941, Xibo Pei, Jian Wang, and co-workers report a silver nanoparticle (AgNPs) modified metal-organic-framework nanosystem ([email protected]) with enhanced photodynamic efficiency chemotherapy ability for infected tissue regeneration. The performance under visible light disrupts bacteria translation process. process causes destructive effect on...

We begin with an introduction of superconductivity by giving a brief history of the phenomenon. The phenomenological Ginzburg–Landau theory and the microscopic theory of Bardeen, Cooper and Schrieffer are outlined. In view of recently available multi-band superconductors, relevant theories of both types are discussed. Unlike the traditional GL theory an extended GL theory is developed relevant ...

We present a model describing the dynamics of a thermally activated nanoelectromechanical device. The nanosystem consisted of two coaxial carbon nanotubes of disparate lengths. The presence of strong thermal inhomogeneities induced motion of the shorter nanotube along the track of the longer nanotube. A model combining the actions of frictional, van der Waals, and thermal forces and the effects...

We predict and quantitatively evaluate the unique possibility of concentrating the energy of an ultra-fast excitation of a nanosystem in a small part of the whole system by means of coherent control (phase modulation of the exciting ultra-short pulse). Such concentration is due to dynamic properties of surface plasmons and leads to local fields enhanced by orders of magnitude. This effect exist...

The sub-wavelength concentration and propagation of electromagnetic energy are two complementary aspects of plasmonics that are not necessarily co-present in a single nanosystem. Here we exploit the strong nanofocusing properties of stacked optical antennas in order to highly concentrate the electromagnetic energy into a 5 nm metal-insulator-metal (MIM) cavity and convert free radiation into gu...

Drug Delivery Systems In article number 2101711, Enza Lonardo, Anna Chiara De Luca, Ilaria Rea, and co-workers demonstrate the small molecule Galunisertib with anticancer activity loaded inside a hybrid multifunctional nanosystem made of porous biosilica covered by plasmonic gold nanoparticles. The pH-triggered-LY release inducing mesenchymal to epithelial transition in colorectal cancer cells ...

The NSDL Materials Digital Library Pathway (MatDL) is utilizing a wiki to facilitate the expert community-driven development of a controlled vocabulary on assembly of nanosystems. Vocabulary development is being initiated using preferred subject terms gathered from Dublin Core metadata captured during the execution of nanoscale computer simulation codes of a research group whose members are def...

We consider the self-assembly of composite structures from a group of nanocomponents, each consisting of particles within an N-atom system. Self-assembly pathways and rates for nanocomposites are derived via a multiscale analysis of the classical Liouville equation. From a reduced statistical framework, rigorous stochastic equations for population levels of beginning, intermediate, and final ag...

Abstract Background Recent studies have demonstrated that multidrug resistance (MDR) is a critical factor in the low efficacy of cancer chemotherapy. The main mechanism MDR arises from overexpression P-glycoprotein (P-gp), which actively enhances drug efflux and limits effectiveness chemotherapeutic agents. Results In this study, we fabricated “combo” nanoagent equipping with triple synergistic...
