l-Dopa@MSNs based on the concept of drug-structure-directing agents were successfully prepared and proved to be programmed oral l-Dopa release nanosystem pH responsive for treatment Parkinson's disease.

Smart drug delivery nanosystem is significant for tumor treatments due to its possibility of temporally, spatially, and dose-controlled release. However, the therapeutic efficacy often compromised in cancer treatment as enrichment agents reticuloendothelial system. Herein, doxorubicin (DOX) loaded biomimetic with macrophage cell membrane (MCM) camouflaged, MnFe2O4-DOX-MCM nanocube (NC), develop...

A fluorinated amphiphilic dendrimer based nanosystem to combat PDAC is reported by Juan Liu and co-workers in the article number 20210003.These nanoparticles markedly overcome heterogeneity of drug response resistance primary tumor cells, constituting a promising delivery system for treatment.

We make a step towards quantum nanoplasmonics: surface plasmon fields of a nanosystem are quantized and their stimulated emission is considered. We introduce a quantum generator for surface plasmon quanta and consider the phenomenon of surface plasmon amplification by stimulated emission of radiation (spaser). Spaser generates temporally coherent high-intensity fields of selected surface plasmo...

The non-classical distribution function formalism is used for studying the electron transport in a nanosystem. We calculated the current–voltage characteristics of a triple barrier one-dimensional nanostructure which is connected to three-dimensional (highly doped semiconductor) reservoirs by the ohmic contacts. We also estimated the peak-to-valley ratio for the considered nanostructure and dis...

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

"Requirements for a sensor that will be sewn into the human heart are completely different than for those found in mobile phones today. The device needs to tolerate other stress factors, as well as meet a number of clinical requirements. The greatest challenge is to make everything small enough so as not to puncture the heart", explained Associate Professor and research leader Kristin Imenes of...
