Development and characterization of potential larvicidal nanoemulsions against Aedes aegypti
Beilstein J. Nanotechnol. 2024, 15, 104–114, doi:10.3762/bjnano.15.10
- characteristics, between 20 and 30 mV, have been described in other studies about nanoemulsions containing terpenes suitable for larvicidal applications [30][33][34]. Regarding the physical characterization, the bluish reflex is characteristic of this type of colloidal system, and it is attributed to the Tyndall
Sputtering onto liquids: a critical review
Beilstein J. Nanotechnol. 2022, 13, 10–53, doi:10.3762/bjnano.13.2
- monodisperse particles and provided a mathematical model for fitting the kinetic curves [89]. As a result, it was applied to any colloidal system, including colloidal dispersions of metal NPs, and finally was considered as “overcited” [90]. In reality, this mechanism describes very well the formation of sulfur
Influence of the magnetic nanoparticle coating on the magnetic relaxation time
Beilstein J. Nanotechnol. 2020, 11, 1207–1216, doi:10.3762/bjnano.11.105
- Langevin dynamics method was applied based on the effective Verlet-type algorithm. The Néel magnetic relaxation time was obtained via the Coffey method in an oblique magnetic field, adapted to the local magnetic field on a nanoparticle. Keywords: colloidal system; effective Verlet-type algorithm; magnetic
Microfluidics as tool to prepare size-tunable PLGA nanoparticles with high curcumin encapsulation for efficient mucus penetration
Beilstein J. Nanotechnol. 2019, 10, 2280–2293, doi:10.3762/bjnano.10.220
- colloidal system, thus minimizing NP agglomeration and nucleation growth [40]. Pluronic F68 was proven to be a muco-inert material [11][47] and was therefore chosen as a stabilizer. The addition of Pluronic F68 (1%) resulted in a slight decrease of the NP diameter to ≈70 nm at 0.05 flow rate ratio in
- the stability of the colloidal system is improved with higher stabilizer concentrations. Therefore, 1% Pluronic F68 might be the most suitable system. Effect of solvent nature and solvent mixture Drug solubility relies fundamentally on the solvent used. Therefore, assessing the influence of the nature
On the relaxation time of interacting superparamagnetic nanoparticles and implications for magnetic fluid hyperthermia
Beilstein J. Nanotechnol. 2019, 10, 1280–1289, doi:10.3762/bjnano.10.127
- nanoparticulate contrasting agents on proton relaxivity [7][8][9]) and cancer therapy (through magnetic fluid hyperthermia therapy [10][11]). The efficiency of the magnetic nanoparticles (MNPs) in a colloidal system to convert the energy of AC magnetic fields into temperature increments is of high importance for
Involvement of two uptake mechanisms of gold and iron oxide nanoparticles in a co-exposure scenario using mouse macrophages
Beilstein J. Nanotechnol. 2017, 8, 2396–2409, doi:10.3762/bjnano.8.239
- in a complex colloidal system, such as the vascular system. The aim of this work was to study the combined effect of two model NPs on cellular uptake, that is gold (AuNPs) and iron oxide NPs (FeOxNPs) stabilized with the same polymer shell and incorporated fluorophores. The NPs can be distinguished
Self-assembly of chiral fluorescent nanoparticles based on water-soluble L-tryptophan derivatives of p-tert-butylthiacalix[4]arene
Beilstein J. Nanotechnol. 2017, 8, 1825–1835, doi:10.3762/bjnano.8.184
- of the compounds 8–11. The zeta potential is another measure of the stability of colloidal systems. The zeta potential characterizes the degree and nature of the interaction between the particles of the disperse system: the larger the electrokinetic potential, the more stable the colloidal system. A
- low zeta potential determines the tendency of the particles of a colloidal solution to coagulate and flocculate. It has been experimentally established [42] that the critical value of the zeta potential corresponding to the stability threshold of a colloidal system is 30 mV. The zeta potential of the
Streptavidin-coated gold nanoparticles: critical role of oligonucleotides on stability and fractal aggregation
Beilstein J. Nanotechnol. 2017, 8, 1–11, doi:10.3762/bjnano.8.1
- entropic interaction associated with a colloidal system in the presence of polymers that are not adsorbed on the surface of colloidal particles [21][22][23][24][25]. This force arises from the difference of the osmotic pressure between the bulk solution and the zone between the surface of the particles
Functionalized platinum nanoparticles with surface charge trigged by pH: synthesis, characterization and stability studies
Beilstein J. Nanotechnol. 2016, 7, 1822–1828, doi:10.3762/bjnano.7.175

Keywords: functionalized platinum nanoparticles; pH responsive materials; synthesis of metal nanoparticles; thiol functionalization; Introduction Metal nanoparticles (MNPs), in particular, platinum nanoparticles (PtNPs) offer a wide range of chemico-physical properties that can be of
- bond on the PtNP surface. The DLS characterization demonstrated the long-term stability of the colloidal system up to three months and the possibility to tune the aggregation phenomenon of the PtNPs by varying the pH due to modulation of the metal surface charge. Experimental Instrumentation UV–vis

- to be formed as observed recently for carbon electrodes [12]. The generated pristine platelets produce a colloidal system under the conditions of their continuous homogeneous nucleation. Most of the layered colloidal systems tend to aggregate if no sufficient electrostatic or steric stabilization is
