“…Some studies have focused on these topics; for example, Mendes et al (2014) found that NPs' cellular uptake is size dependent, so the toxicological process is influenced by this parameter. Besides, it has been established that wire-shaped silver NPs cause higher cytoxicity than spherical ones on alveolar epithelial cells (Stoehr et al 2011).…”

Novel nanoinsecticides based on essential oils to control the German cockroach

The physicochemical characterization and residual insecticidal activity of poly(ethylene glycol) (PEG) nanoparticles containing essential oils (EOs) from geranium (Geranium sp.) and bergamot (Citrus reticulata L.) were evaluated against Blatella germanica for 1 year. The nanoparticles' size increased during the storage time from \235 to \450 nm; the EO content decreased approximately 50 %, and the abundance of the major components did not show any differences between pre-and post-formulation. The surface characteristics of nanoparticles were analyzed by transmission electronic microscopy. The EO nanoparticles produced a notable increase in the residual contact toxicity apparently because of the slow and persistent release of the active terpenes. In addition, the nanoformulation enhanced the EO contact toxicity. The results indicate that these novel systems could be developed as control agents against German cockroaches.

“…Additionally, degradation of iron oxide into free ions in physiological environments [9] has been reported to increase free radical production in cells, causing damage which may lead to cell death [10,11]. Therefore, these particles are commonly coated with organic macromolecules, such as poly(acrylic acid) (PAA) [12], dextran [13], and poly(ethyleneimine) (PEI) [14] or with coatings such as silica [15], carbon [16], or precious metals (e.g., gold or silver) [17]. In light of the unique properties of MNPs, particularly iron oxide NPs, the aim of this review is to discuss the recent developments in the synthesis and application of iron oxide NPs.…”

A biotechnological perspective on the application of iron oxide nanoparticles

In recent decades, magnetic iron nanoparticles (NPs) have attracted much attention due to properties such as superparamagnetism, high surface area, large surface-to-volume ratio, and easy separation under external magnetic fields. Therefore, magnetic iron oxides have potential for use in numerous applications, including magnetic resonance imaging contrast enhancement, tissue repair, immunoassay, detoxification of biological fluids, drug delivery, hyperthermia, and cell separation. This review provides an updated and integrated focus on the fabrication and characterization of suitable magnetic iron NPs for biotechnological applications. The possible perspective and some challenges in the further development of these NPs are also discussed.

The impact of doped silicon quantum dots on human osteoblasts

Silicon (Si) nanostructures allow for the expansion of the application spectrum of this important semiconductor material with respect to the fields of optoelectronics and photonics. At the same time, the significant potential of Si quantum dots (SiQDs) has been revealed in terms of their potential application in the areas of biology and medicine due to their biocompatibility, low toxicity and natural biodegradability unlike currently used semiconductor quantum dots. As far as this study is concerned, SiQDs co-doped with boron and phosphorus were used for the in vitro evaluation of their cytotoxicity in human osteoblasts. Two chemically identical types of SiQD differing in terms of their size and photoluminescence (PL) were studied. They both display long-lasting dispersion in methanol and even in aqueous media as well as PL which is not sensitive either to changes in the environment or surface modifications. Our experiments revealed significant differences between the two types of SiQD tested with concern to their behavior in a cell culture environment depending on increasing concentration (25 -125 µg/ml) and cultivation conditions (the presence or absence of proteins from the fetal bovine serum -component of the cultivation medium). Detailed description of their optical parameters and the evaluation of zeta potential enhance the understanding of the complexities of the in vitro results obtained.
