Electroporation is a simple yet powerful technique for breaching the cell membrane barrier. The applications of electroporation can be generally divided into two categories: the release of intracellular proteins, nucleic acids and other metabolites for analysis and the delivery of exogenous reagents such as genes, drugs and nanoparticles with therapeutic purposes or for cellular manipulation. I...

In recent years, rapid advancements have been made in the biomedical applications of micro and nanotechnology. While the focus of such technology has primarily been on in vitro analytical and diagnostic tools, more recently, in vivo therapeutic and sensing applications have gained attention. This paper describes the creation of monodisperse nanoporous, biocompatible, silicon membranes as a plat...

BACKGROUND Gp91(phox) is a transmembrane protein and the catalytic core of the NADPH oxidase complex of neutrophils. Lack of this protein causes chronic granulomatous disease (CGD), a rare genetic disorder characterized by severe and recurrent infections due to the incapacity of phagocytes to kill microorganisms. METHODOLOGY Here we optimize a prokaryotic cell-free expression system to produc...

In article number 2001212 by Huile Gao, Xianchun Chen, and co-workers, recent progress of self-propelled micro/nanomotors for tumor drug delivery is reviewed. The force facilitates with autonomous movement, therefore exhibit potential enhanced efficiency in each step delivery, which includes circulation the blood, targeting, deep penetration, cellular internalization, release. combination thera...

This paper briefly reviews the recent progress in using layered double hydroxide (LDH) nanomaterials as cellular delivery agents. The advantages of LDHs as cellular delivery agents are summarized, and the processes of interaction/de-intercalation of anionic drugs (genes) into/from LDH nanoparticles are discussed. Then the cellular delivery of LDH-drug (gene) nanohybrids and subsequent intracell...

background: the poor permeability of the plasma and nuclear membranes to dna plasmids are two major barriers for the development of these therapeutic molecules. therefore, success in gene therapy approaches depends on the development of efficient and safe non-viral delivery systems. objectives: the aim of this study was to investigate the in vitro delivery of plasmid dna encoding hpv16 e7 gene ...

Cationic polymeric nanoparticles have great potential for developing drug delivery systemswith limited side effects for tumor medication. The goal of this research is investigation ofcationic dextran-spermine polymer (DS) efficacy for improvement of hydrophilic drug deliveryto negatively charged cancerous cells. Capecitabine (as a hydrophilic antineoplastic drug) wasloaded into the magnetic dex...
