Nanocomposites with antibacterial properties using CNTs with magnetic nanoparticles

Nanoscale systems occupy the most important place among the vehicles intended for targeted drug delivery. Such vehicles are considered in this review. Attention is paid to the nanocluster polyoxometalate-based systems which are promising for transdermal iontophoretic transport. In this relation, and due to the characteristics of the skin as a transport medium, the problems of the transfer processes modeling are considered.

“…AgNP-loaded CNT and TiO 2 nanotubes possess high efficiency in photocatalytic applications [6][7][8] including antibacterial photocatalysis in visible light [9]. Additionally, Ag-CNT nanocomposites are considered promising gas sensors [10,11], catalysts [12], antibacterial agents [13][14][15] and drug delivery carriers [16].…”

Two facile routes for functionalization of WS2 nanotubes with silver nanoparticles

et al. 2017

Silver-coated WS 2 nanotubes (NT-WS 2 ) were successfully synthesized via two wet chemistry techniques. The first employs spontaneous silver nanoparticle growth resulting from an interaction of disulfide nanotubes with AgNO 3 in aqueous suspensions at 100• C without any additional reducing agents or stabilizers. The second utilizes [Ag(NH 3 ) 2 ]OH complex to produce silver nanoparticles upon thermal decomposition. Both techniques are capable of producing Ag-NT-WS 2 nanocomposites containing 5-60 nm silver nanoparticles tightly attached to the nanotubes' surfaces. The hexagonal arrangement of sulfur atoms of the outer WS 2 layer was postulated to facilitate crystallization of silver nanocrystals with hexagonal crystallographic system (4H-Ag). The physical-chemical model for spontaneous AgNP formation is proposed.

Mathematical modeling of magnetic field guided colloidal particle deposition with significant electric double layer interactions

et al. 2017

In this work, we propose a simple theoretical method for predicting the rate and localization of magnetic field guided particle deposition from aqueous colloids. This method accounts for the colloidal electric double layer interactions between particles and vessel walls. The obtained results suggest that the colloidal interactions can be used to increase the rate of particle deposition and improve its localization.
