- milling speed but reduced heat damage. Keywords: biological sample; COMSOL; focused ion beam; forward time–centered space (FTCS); heat damage; SRIM; Introduction FIB-SEMs combine a scanning electron microscope (SEM) and a focused ion beam (FIB) in a single instrument and are increasingly used to prepare
Bio-imaging with the helium-ion microscope: A review
Beilstein J. Nanotechnol. 2021, 12, 1–23, doi:10.3762/bjnano.12.1
Nitrogen-vacancy centers in diamond for nanoscale magnetic resonance imaging applications
Beilstein J. Nanotechnol. 2019, 10, 2128–2151, doi:10.3762/bjnano.10.207
- experiment possible was to bring an NV layer sensor to within ≈10 μm from the specimens, while all other methods (e.g., sensitive superconducting quantum interference devices (SQUIDs)) are limited by distances of millimeters or more from the biological sample. Even with a sensitivity of fT·Hz−1/2, the
- thermal (dissipation) damage to the biological sample. For a given minimal and microwave probe power, NV photon emission was enhanced by the optical collection design of the magnetometer, achieved through increasing the NV concentration and by using SiC as a substrate to aid in heat transfer. After
Experimental study of an evanescent-field biosensor based on 1D photonic bandgap structures
Beilstein J. Nanotechnol. 2019, 10, 967–974, doi:10.3762/bjnano.10.97
- , biofunctionalization is a key step for providing a label-free biosensing device able to analyze a chemical or a biological sample without requiring any pre-treatment (as for example labeling). Since the operation of photonic biosensors based on evanescent waves relies on the interaction between the target analytes and
Ultraviolet patterns of flowers revealed in polymer replica – caused by surface architecture
Beilstein J. Nanotechnol. 2019, 10, 459–466, doi:10.3762/bjnano.10.45
- mold is generated followed by a positive. For the generation of the negative, the master (biological sample) is molded with a polyvinylsiloxane dental wax (President light body gel, ISO 4823, PLB; Coltene Whaldent, Hamburg, Germany). In the second step, these molds are filled with a two-component
The structural and chemical basis of temporary adhesion in the sea star Asterina gibbosa
Beilstein J. Nanotechnol. 2018, 9, 2071–2086, doi:10.3762/bjnano.9.196
- adhesive might help in designing new biomimetic glues. Experimental Maintenance of animals Individuals of Asterina gibbosa (Pennant, 1777) were obtained from the Biological Sample Collection Service of the Station Biologique de Roscoff, France. They were kept in a marine aquarium with closed circulation
Low temperature co-fired ceramic packaging of CMOS capacitive sensor chip towards cell viability monitoring
Beilstein J. Nanotechnol. 2016, 7, 1871–1877, doi:10.3762/bjnano.7.179
- viability screening are lethal to the cells. Hence there is a growing interest in noninvasive, label-free, real-time, data-rich biosensing systems that measure electrical, optical, magnetic, or mass related properties of the biological sample. Such sensing techniques include surface plasmon resonance
An ISA-TAB-Nano based data collection framework to support data-driven modelling of nanotoxicology
Beilstein J. Nanotechnol. 2015, 6, 1978–1999, doi:10.3762/bjnano.6.202
- in the “Source Name” column, from which a sample is prepared for testing in an assay and the originally sourced nanomaterial is considered a “factor”, since the effect of adding this nanomaterial to the biological sample being prepared for evaluation is studied: the corresponding Material file
- of the nanomaterial will be evaluated. Hence, they are designed to capture different kinds of experimental variables: (1) those which are relevant to preparation of the biological sample prior to adding the nanomaterial, e.g., the “Factor Value [culture medium glucose supplement]” in
- “s_InvID_InVitro.CB.xls” designed to record whether or not the cells were grown in glucose containing “culture medium”, which may significantly affect the observed toxicity in some in vitro assays [56]; (2) those which are relevant to the preparation of the nanomaterial sample applied to the biological sample, e.g
Overview about the localization of nanoparticles in tissue and cellular context by different imaging techniques
Beilstein J. Nanotechnol. 2015, 6, 263–280, doi:10.3762/bjnano.6.25
- biological sample and the use of labels [126][127][128]. Intrinsic chemical bond vibrations can be visualized and characterized combined with optical sectioning with diffraction-limited spatial resolution that can be approximated to 1 µm [129][130]. This technique has been used, for example, in in vivo and
Hierarchically structured superhydrophobic flowers with low hysteresis of the wild pansy (Viola tricolor) – new design principles for biomimetic materials
Beilstein J. Nanotechnol. 2011, 2, 228–236, doi:10.3762/bjnano.2.27
- Koch et al. [28] was used. Here, we briefly introduce the technique and mention the modifications made. The replication technique is a two-step moulding process, in which at first a negative is generated and then a positive. For generating the negative replicas, the master (biological sample) is
