“…The PEG-coated SPIONs exhibited a longer blood circulation time than dextran-coated SPIONs [ 39 ], having better colloidal stability and reduced agglomeration tendency. In addition, very importantly, the PEG coating did not degrade the magnetization properties of the nanoparticles [ 82 ]. Chen et al [ 40 ] showed that SPIONs functionalized with PEG, grafted with polyethyleneimine and conjugated with CD44 siRNA can be used as non-viral gene therapy vectors.…”

Superparamagnetic iron oxide nanoparticles (SPIONs) have unique properties with regard to biological and medical applications. SPIONs have been used in clinical settings although their safety of use remains unclear due to the great differences in their structure and in intra- and inter-patient absorption and response. This review addresses potential applications of SPIONs in vitro (formulations), ex vivo (in biological cells and tissues) and in vivo (preclinical animal models), as well as potential biomedical applications in the context of drug targeting, disease treatment and therapeutic efficacy, and safety studies.

“…[6] Furthermore, PVA and PVP are desired owing to their hydrophilicity influence, ecofriendly, nontoxicity, and biocompatible as an organic passivating agent on nano materials; they were used differently for the encapsulation of different nano materials to increase the colloidal stability, fine size distribution and decrease agglomeration. [7][8][9] The PVA/PVP blend can be formed with any ratio due to the water solubility of PVA and PVP, where the interactions between PVA and PVP can happen via interchain hydrogen bonding between carbonyl and hydroxyl groups of PVP and PVA, respectively. [10] Furthermore, the properties of the polymer or the blend can also further improve by doping it with suitable inorganic nano oxides or sulfides materials in order to increase its applications.…”

PVA/PVP blend embedded with different ratios of nano Cu0.9Mn0.1S (Cu/MnS) was prepared with thermolysis and casting techniques. X‐ray diffraction analysis showed the formation of nano Cu/MnS as a single hexagonal phase with an average crystallite size 11 nm. Scanning electron microscope (SEM) revealed nearly homogenous particles morphology. Fourier transform infrared (FTIR) spectroscopy technique was applied to characterize the Cu/MnS doped PVA/PVP matrix. UV measurements were utilized to investigate the optical properties in detail. Upon doping with Cu/MnS, the bandgap of PVA/PVP was significantly decreasing with the amount of doping; which enabling tailoring the band gap depending on the doping content. The analysis showed that the main possible transitions in pure PVA/PVP blend are indirect allowed and direct forbidden. On the other hand, for the doped blend samples, the direct allowed is the main possible transition. Moreover, the refractive index and the real and imaginary parts of the dielectric constant increased upon increasing the Cu/MnS amount doped.

“…This method involves synthesis protocols that use innocuous, facile, eco-friendly, cost-effective, biocompatible and biodegradable materials as a potential reducing and capping agents. It involves the use of green technology such as microorganisms [48], biopolymers [49,50,16,51,52,53], extracts from leaves [54,14,15,17,15,16,55,56], extract from fruits and seeds of plants [57,58,59] as a potential reducing and capping agents [13,14,17,15,55]. This approach is gaining much attention in contemporary nanotechnology [60,61,62].…”

In-situ biosynthesis of silver nanoparticles for antibacterial activities doped with aqueous extract of dry Gongronema Latifolium (DGL) is presented in this work. The absorbance was determined using a UV-Visible analysis with a peak of 428 nm. The obtained particles confirmed by the TEM image analysis were spherical in shape with an average particle size between 5 and 20 nm. A single crystalline phase of FCC was confirmed by the powder. The functional groups showed the phytochemical inherent in the sample. The colloidal solution of DGL-AgNPs with MIC of 10 µg/ml showed a noteworthy functional susceptibility against the bacterial strains, particularly, K. pneumonia with susceptibility greater than gentamicin. Based on these observations, the formulated DGL-AgNPs show strong bactericidal against the pathogens with facile, benign, eco-friendly, biocompatibility and innocuous synthesis procedures. This can serve as an efficient bactericidal agent.
