Nanoparticles are engineered particles of between one and 100 nanometers in diameter, a size known as the nanoscale. To put this into context, a nanometer (nm) is one billionth of a meter, and the distance between individual atoms in a solid is between 0.1 nm and 0.4 nm. Nanoparticles the...
Dispersion of Nanoparticles in Pulmonary Surfactants for In Vitro Toxicity Studies: Lessons from Ultrafine Diesel Exhaust Particles and Fine Mineral Dusts Nanostructured materials including nanoparticles (NP) are generally defined as having at least one dimension smaller than 100 nm ( 1 ). Ultrafine ...
The aerosol contained particles >1 µm comprised of tin, silver, iron, nickel, aluminum, and silicate and nanoparticles (<100 nm) of tin, chromium and nickel. The concentrations of nine of eleven elements in EC aerosol were higher than or equal to the corresponding concentrations in ...
Nanoparticles and nanocarriers can be used for delivery of peptide drugs to specific sites of interest, avoiding degradation in the GIT and first-pass metabolism via the hepatic route. In fact, peptides have been transported using nanocarriers. Hyaluronic acid–Fe2O3 hybrid magnetic nanoparticles ...

The field of dentistry has incorporated the use of advanced technology to manufacture nanoparticles (NPs). The uses of these materials are diverse and encompass caries inhibitors, biomembranes, scaffolds, and targeted medication transfer [8]. These emerging technologies have the potential to advance ...
The invention refers to mineral particles, which are characterized by containing acceptable minerals and carriers, in which nanoparticles are between 50 and 600 nanometers in size and have pharmaceutical applications. Food and cosmeticsHERNANDEZ SANDOVAL, GUSTAVO RAFAEL...
Albumin nanoparticles preparation ABNPs can be generated via three primary mechanisms: desolvation, emulsification, and thermal gelation. Recently, nano-spray drying, Nab-technology, and self-assembly approaches have been utilized [67]. ABNPs can be produced using either chemical or physical processes....
aIn Figure 1b, that depicts the SiC nanoparticles, while there seem to be particles on the order of 200 nm across, the all of the particles in the field of view of the micrograph seem to be agglomerated into a single particle. Other nanoparticles obtained from other vendors are often ...
Chiral active particles (CAPs) are self-propelling particles that break time-reversal symmetry by orbiting or spinning, leading to intriguing behaviors. Here, we examined the dynamics of CAPs moving in 2D lattices of disk obstacles through active Brownia
