Studies of probe tip materials by atomic force microscopy: a review
Beilstein J. Nanotechnol. 2022, 13, 1256–1267, doi:10.3762/bjnano.13.104
- -recognition probe ("sandwich" complex) and measured by matrix-assisted laser resolved ionization time-of-flight mass spectrometry (MALDI–TOF MS). Ultra-pure water (as a blank control), perfectly matched DNA, incompletely matched DNA, and two DNA fragments with only one base mismatch were added to the system
Structural and optical properties of penicillamine-protected gold nanocluster fractions separated by sequential size-selective fractionation
Beilstein J. Nanotechnol. 2019, 10, 955–966, doi:10.3762/bjnano.10.96
- only is the size distribution of the AuNCs narrowed, but also the excess free ligand, disulfide and gold(I) complex, can be removed. Mass spectrometry and thermogravimetric studies of SSSP fractions Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI–MS) is an effective
Green synthesis of fluorescent carbon dots from spices for in vitro imaging and tumour cell growth inhibition
Beilstein J. Nanotechnol. 2018, 9, 530–544, doi:10.3762/bjnano.9.51
- , Germany) and the C-dots samples were prepared on a glass substrate. Fourier transform infrared (FTIR) spectra were recorded using a Perkin Elmer Spectra 100 FTIR Spectrometer (Perkin Elmer, USA). Electrospray ionization coupled to quantitative time of flight mass spectrometry measurements were performed
Recombinant DNA technology and click chemistry: a powerful combination for generating a hybrid elastin-like-statherin hydrogel to control calcium phosphate mineralization
Beilstein J. Nanotechnol. 2017, 8, 772–783, doi:10.3762/bjnano.8.80
- purification, ELRs were characterized using matrix-assisted laser deposition ionization time of flight mass spectrometry (MALDI-TOF-MS), attenuated total reflection infrared spectroscopy (ATR-IR) and nuclear magnetic resonance spectroscopy (1H NMR). 3 Preparation of ELR hydrogels ELR hydrogels were made by
- different incubation times (4, 8, and 14 days) by removing and rinsing with ultrapure water followed by drying under vacuum at 37 °C. 6 Analysis 6.1 Matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS) The molecular weight (Mw) of the ELRs was determined by MALDI-TOF
Nitrogen-doped twisted graphene grown on copper by atmospheric pressure CVD from a decane precursor
Beilstein J. Nanotechnol. 2017, 8, 145–158, doi:10.3762/bjnano.8.15
- magnitude smaller than for a N2 dissociation process. For example, for the •CH + N2 = N + •CHN reaction this value was determined as 21.2 ± 0.7 kcal/mol [66]. Moreover, as it was proved by time-of-flight mass spectrometry experiments, various hydrocarbon radicals can be formed from n-decane just by thermal
Femtosecond time-resolved photodissociation dynamics of methyl halide molecules on ultrathin gold films
Beilstein J. Nanotechnol. 2011, 2, 618–627, doi:10.3762/bjnano.2.65
- at all. Keywords: femtosecond laser spectroscopy; gold; methyl halide photodissociation; surface chemistry; time-of-flight mass spectrometry; Introduction The understanding of the mechanisms involved in the light-induced excitation and fragmentation of organic molecules on metal substrates is of
- free molecule [3] cannot be energetically lowered enough to become accessible to the 4.7 eV photons of the 266 nm pump laser beam. Conclusion The present investigation demonstrates that time resolved pump–probe fs-laser time-of-flight mass spectrometry is able to probe the photodissociation dynamics of
