The field of gene therapy still attracts great interest due to its potential therapeutic effect towards the most deadly diseases, such as cancer. For cancer gene therapy to be feasible and viable in a clinical setting, the design and development of a suitable gene delivery system is imperative. Peptide based vectors, in particular, reveal to be pro...

In this study, we found that Fe3O4 promoted horizontal gene transfer (HGT), but when Fe3O4 was composited with MoS2, the [email protected] nanocomposite interacting with bacteria significantly blocked the HGT in the conjugation system. qPCR was used to analyze the expression of genes belonging to the chromosome and plasmid in the conjugation system. Resul...

In this paper, the dispersion performance of biomacromolecule hydrolyzed cellulase from Trichoderma reesei on copper phthalocyanine (CuPc) pigment was first studied. The effect of hydrolysis time, cellulase concentration and environmental pH on the dispersion performance was investigated by particle size distribution and suspension transmittance me...

pH-responsive nanocarriers such as polymeric micelles that self-assemble from amphiphilic copolymers containing amino groups have been limited by their significant effects on the blood and thus compromise of their hemocompatibility due to the amino group-induced positive charges. Here we report a biomimetic phosphorylcholine strategy to improve the...

Cell separation methods that do not require surface modification of cells are needed in tissue engineering and regenerative medicine. We developed thermoresponsive anionic polymer brushes for cell separation without modification of the cell surfaces. Copolymer brush poly(N-isopropylacrylamide-co-N-tert-butylacrylamide-co-tert-butyl acrylate, P(NIPA...

Drug solubility and permeability are two major challenges affecting oral delivery, the most popular route of drug administration. Polymeric micelles is an emerging technology for overcoming the current oral drug delivery hurdles. Previous study primarily focused on developing new polymers or new micellar systems and a systematic investigation of th...

Classical extraction methods used for an isolation of active substances from the plant material are expensive, complicated and often environmentally unfriendly. The ultrasonic assistance micelle-mediated extraction method (UAMME) seems to be an interesting alternative. The aim of this work was to compare an efficiency of water solutions of three no...

In this study synthesis of graphene oxide-poly citric acid/MnCe0.5Fe1.5O4 nanoferrofluid with a simple method and its ability for enhancing the contrast of magnetic resonance images was reported. The co-precipitation method has been used for the production of MnCe0.5Fe1.5O4 nanoparticles with a size distribution of 25-40 nm, which has shown a very ...

In this paper, a bottom-up hydrothermal route is reported for the synthesis of oxygen and nitrogen co-decorated carbon quantum dots (CQDs) using ammonium hydrogen citrate (AHC) as a single precursor. DLS data approved the formation of 4.0 nm (average size) CQDs. XRD pattern shows the interlayer spacing (002) of 3.5 Å for CQDs, which is exactly the ...

Taking into account that modified and non modified TiZr alloys have a chance as alternatives for Ti as implant materials, this paper is focused on the elaboration and characterization of TiZr hybrid nanostructures (nanopores and nanotubes) loaded with gentamicin (GS) and covered with chitosan. FT-IR analysis permitted structure and corresponding ba...
