Flash nanoprecipitation (FNP) has proven to be a powerful tool for the rapid and scalable assembly of solid-core nanoparticles from block copolymers. The process can be performed using a simple confined impingement jets mixer and provides an efficient and reproducible method of loading micelles with hydrophobic drugs. To date, FNP has not been applied for the fabrication of complex or vesicular nanoarchitectures capable of encapsulating hydrophilic molecules or bioactive protein therapeutics. Here, we present FNP as a single customizable method for the assembly of bicontinuous nanospheres, filomicelles and vesicular, multilamellar and tubular polymersomes from poly(ethylene glycol)-bl-poly(propylene sulfide) block copolymers...

Increased use of fullerols in various fields and expected increase of their environmental spread impose the necessity for testing fullerol nanoparticles (FNP) effects on microbiota. There is little information available on the interaction of mycotoxigenic fungi and FNP, despite FNP having a great potential of modifying mycotoxin production. Namely, FNP exhibit both ROS-quenching and ROS-producing properties, while oxidative stress stimulates mycotoxin synthesis in the fungi. In order to shed some light on the extent of interaction between FNP and mycotoxigenic fungi, the effects of fullerol C60(OH)24 nanoparticles (10, 100, 1000 ng/mL) on mycelial growth, aflatoxin production and oxidative stress modulation in an aflatoxigenic strain of Aspergillus flavus (NRRL 3251) during 168 h of incubation in a liquid culture medium were examined...

Campus health centers are a convenient, and usually affordable, location for college students to obtain health care. Staffed by licensed and trained professionals, these providers can generally offer similar levels of care that providers at off-campus clinics can deliver. Yet, previous research finds students may forgo this convenient, on-campus option partially because of a lack of knowledge regarding the quality of providers at these campus clinics. This study sought to examine where this information deficit may come from by analyzing campus health centers' online provider information...

Immunochromatographic assays (ICA) are widely used to detect pathogens. In this study, we used traditional gold nanoparticles (GNP), quantum dots (QD), fluorescent nanoparticles (FNP), and europium (Eu) (III) chelate nanoparticles (EuNP) as ICA labels. We first compared the ability of the 4 ICA test strips to quantitatively detect Escherichia coli O157:H7 in milk. We then optimized various parameters influencing the ICA. The sensitivity to E. coli O157:H7 of the GNP-ICA, QD-ICA, FNP-ICA, and EuNP-ICA was 2...

Geometrically structured polymer nanocolloids, including Janus nanocolloids, have been widely investigated for their unique properties, which are derived from their anisotropy. Controlled surface decoration with inorganic nanoparticles could induce another level of functionality into structured nanocolloids that could enable applications in fields ranging from rewriteable electronics to biphasic catalysis. Here, we demonstrate flash nanoprecipitation (FNP) as a one-step, scalable process platform for manufacturing hybrid polymer-inorganic nanocolloids in which one phase is selectively decorated with a metal nanocatalyst by tuning the molecular interactions between the feed ingredients during the process...

Doxorubicin (DOX), commonly used antineoplastic agent, affects bone marrow, intestinal tract and heart, but it also has some hepatotoxic effects. Main mechanism of its toxicity is the production of free reactive oxygen species. Polyhidroxilated C60 fullerene derivatives, fullerenol nanoparticles (FNP), act as free radical scavengers in in vitro systems. The aim of the study was to investigate potential FNP protective role against DOX-induced hepatotoxicity in rats. Experiments were performed on adult male Wistar rats...

Facial nerve paralysis (FNP) after super-selective intra-arterial chemotherapy (SSIAC) is a relatively rare local side effect of SSIAC to the maxillary artery (MA) or the middle meningeal artery (MMA). The incidence and prognosis of FNP after SSIAC in 381 patients with oral cancer (133 with catheterization of the MA, 248 without) was investigated retrospectively. Only three patients (two male and one female) had FNP, for an incidence of 0.8%. All patients with FNP had undergone catheterization of the MA, and the incidence of FNP in this group was 2...

We present a combined nanoparticle (NP) formation process and spray drying to create a nano-matrix formulation of cyclosporine A (CsA) and mannitol (nCsA/MAN) to increase the bioavailability of CsA. CsA NPs were prepared by flash nano precipitation (FNP) using a multi-inlet vortex mixer, and spray-dried with or without mannitol to prepare nCsA/MAN or nanoprecipitated CsA powder (nCsA), respectively. Pre-forming the NPs by FNP uncouples the sizes of the CsA inclusions from the ultimate micron-sized powders produced by spray drying...
