Highly porous copper-supported magnetic nanocatalysts: made of volcanic pumice textured by cellulose and applied for the reduction of nitrobenzene derivatives

Abstract

Herein, a novel designed heterogeneous catalytic system constructed of volcanic pumice magnetic particles (VPMPs), cellulose (CLS) as a natural polymeric matrix, and copper nanoparticles (Cu NPs) is presented.

Effects of morphology and size of nanoscale drug carriers on cellular uptake and internalization process: a review

“…4 There have been various studies on drug carriers utilized in drug delivery systems with diverse characteristics in recent decades. 5–11 Among them all, nanocarriers are a broad subset that has attracted much more attention because of their small and nanoscale dimensions, which leads to better loading and uptake into the cell, 12 and can be applied in many fields, such as catalysis, 13–39 photocatalysis, 40–42 solar cells, 43–45 and environmental aspects. 46–49 This advantage also enhances smart and targeted drug delivery.…”

Synergies in antimicrobial treatment by a levofloxacin-loaded halloysite and gold nanoparticles with a conjugation to a cell-penetrating peptide

“…[10][11][12] In the broad spectrum of naturalbased materials, clay-based nanostructures such as montmorillonite, bentonite, perlite, and other silicate materials have shown a substantial potential to be exploited in different applications. [13][14][15] Among all claybased species, halloysite nanotubes (HNTs), one of the most well-known clay materials, are particularly preferred for drug delivery due to their unique morphology. [16][17][18] According to literature, the rod-shaped morphology (also needles and tubes) of the drug carriers significantly affects the cell adhesion, internalization, and uptake processes.…”

Nanoscale bioconjugates: A review of the structural attributes of drug-loaded nanocarrier conjugates for selective cancer therapy
