- - Universitätsmedizin Berlin (EA4/023/22). Blood samples were processed immediately after blood collection, and cell metabolism was maximally slowed down by storage at 0 °C. Particle preparation For the preparation of hemoglobin-based sub-micron particles (HbMPs), the protocol of particle preparation using the CCD
Two-step single-reactor synthesis of oleic acid- or undecylenic acid-stabilized magnetic nanoparticles by thermal decomposition
Beilstein J. Nanotechnol. 2023, 14, 11–22, doi:10.3762/bjnano.14.2
- reaction conditions (e.g., time, temperature, purity, or ratio of reagents) considerably influence the properties of the obtained nanoparticles [16]. Besides the narrow size distribution of the particles obtained by thermal decomposition, particle preparation with various morphologies (e.g., spherical
Bacterial safety study of the production process of hemoglobin-based oxygen carriers
Beilstein J. Nanotechnol. 2022, 13, 114–126, doi:10.3762/bjnano.13.8
- . Additionally, HbMP were prepared with a spiked hemoglobin solution as well as under standard process conditions as a control. Hemoglobin microparticles – size, zeta potential, morphology In addition to particle preparation with spiked hemoglobin, particles were also prepared using the standard protocol. The
- for Gram-negative bacteria, especially E. coli [29][58]. However, EDTA can also lead to inhibition of growth and cell lysis in Gram-positive bacteria [59][60]. In the study presented here, EDTA is used to dissolve the carbonate template during particle preparation at a concentration of 0.2 M. The
- results of our experiments (Figure 4) are in agreement with the abovementioned literature. Combination of glutaraldehyde and EDTA according to the particle preparation routine In addition to the experiments described above, in which the effect of glutaraldehyde and EDTA was separately examined, both
The different ways to chitosan/hyaluronic acid nanoparticles: templated vs direct complexation. Influence of particle preparation on morphology, cell uptake and silencing efficiency
Beilstein J. Nanotechnol. 2019, 10, 2594–2608, doi:10.3762/bjnano.10.250
Synthesis of nickel/gallium nanoalloys using a dual-source approach in 1-alkyl-3-methylimidazole ionic liquids
Beilstein J. Nanotechnol. 2019, 10, 1754–1767, doi:10.3762/bjnano.10.171
- -induced decomposition. Furthermore, additional particle size distributions, XP spectra and catalytic results, as well as particle preparation descriptions are given. Supporting Information File 126: Additional experimental details. Acknowledgements Authors are thankful to the Deutsche
Evaluation of preparation methods for suspended nano-objects on substrates for dimensional measurements by atomic force microscopy
Beilstein J. Nanotechnol. 2017, 8, 1774–1785, doi:10.3762/bjnano.8.179
- substrates. Several known and proven particle preparation methods, i.e., membrane filtration, drying, rinsing, dip coating as well as electrostatic and thermal precipitation, were performed by means of scanning electron microscopy to examine their suitability for preparing samples for dimensional AFM
- dedicated equipment and led to a uniform local distribution of individualized nano-objects. Traceable AFM measurements based on Si and SiO2 coated substrates confirmed the suitability of this technique. Keywords: atomic force microscope; nano-object; particle preparation; Introduction Today
- accurate measurement of the particle size, the height measurement should be used. Preparation methods Particle preparation methods for analysis by electron microscope typically consist of three main stages: pre-conditioning of the initial sample (e.g., homogenisation, dilution) and the substrate (e.g
pH-Triggered release from surface-modified poly(lactic-co-glycolic acid) nanoparticles
Beilstein J. Nanotechnol. 2015, 6, 2504–2512, doi:10.3762/bjnano.6.260
- use of nanoparticles as drug delivery systems has been intensively investigated and important progress has been made within the past decades, establishing reliable methods for particle preparation and characterization. Formation of nanostructures based on different materials, such as metals [1
- , terminating the particle preparation. Figure 4 shows the resulting particle sizes and zeta potentials after each step of the nanoparticle modification, which underlines the successful preparation, demonstrated by a constant size and an inversion of the zeta potential after each adsorption step. Release of
- a pH stimulus. Nanoparticle preparation: PLGA nanoparticles were prepared by a modified emulsion diffusion method. The addition of a stabilizing agent is generally favoured due to increased final particle stability. Here, poly(vinyl alcohol) (PVA) was used for particle preparation since it has
Extended X-ray absorption fine structure of bimetallic nanoparticles
Beilstein J. Nanotechnol. 2011, 2, 237–251, doi:10.3762/bjnano.2.28
- probably due to a lack of a sufficient number of vacancies. A method to destabilise the icosahedral shape, and to promote the formation of single-crystalline fcc FePt nanoparticles, is the introduction of oxygen during particle preparation [81]. However, the formation of the L10 phase was not observed
Review and outlook: from single nanoparticles to self-assembled monolayers and granular GMR sensors
Beilstein J. Nanotechnol. 2010, 1, 75–93, doi:10.3762/bjnano.1.10
- we further analyze different properties of granular giant magnetoresistance sensors based on their spin-dependent transport properties. Review 1. Particle preparation In principle, two different strategies for the synthesis of nanoparticles may be pursued. The top-down method starts from the bulk
