Facile synthesis of size-tunable L-carnosine-capped silver nanoparticles and their role in metal ion sensing and catalytic degradation of p-nitrophenol
Beilstein J. Nanotechnol. 2024, 15, 1576–1592, doi:10.3762/bjnano.15.124
- -car-AgNPs for both heavy metal ion detection and catalytic degradation of P-NP, indicating their suitability for environmental monitoring and remediation applications. Further optimization and research are needed to expand their environmental applications and to understand their interaction mechanisms
Nanoarchitectonics with cetrimonium bromide on metal nanoparticles for linker-free detection of toxic metal ions and catalytic degradation of 4-nitrophenol
Beilstein J. Nanotechnol. 2024, 15, 1312–1332, doi:10.3762/bjnano.15.106
- , metal composition, centrifugation, and NaOH amount, were investigated for their impact on the performance of CTAB-capped nanoparticles in heavy metal detection and 4-NP degradation. CTAB-Au nanospheres demonstrated limited heavy metal ion detection capability but exhibited remarkable efficiency in
- many applications, which in some instances require an external linker or ligand for usable applications. It was reported that for CTAB-capped nanoparticles to enable sensing, the use of a linker on CTAB was mandatory for heavy metal ion detection. Linker-free detection of heavy metals using CTAB is a
- did not detect any metal ions. A subtle change in capping concentration on AuNR1 and AuNR2 was observed due to their length (Table 1). The change in concentration or size of nanorods ultimately affects the sensitivity towards metal ion detection. The metal selectivity was observed for all metal ions

Soybean-derived blue photoluminescent carbon dots
Beilstein J. Nanotechnol. 2020, 11, 606–619, doi:10.3762/bjnano.11.48
- wavelength [7], and low cost [8]. CDs have been considered as a group of important nanomaterials with potential applications in nanotechnology [9], electrocatalysis [10], metal-ion detection [2], thermal sensing [11], drug delivery [12], and biosensing and bioimaging [1]. Several methods are available for
Selective detection of Mg2+ ions via enhanced fluorescence emission using Au–DNA nanocomposites
Beilstein J. Nanotechnol. 2017, 8, 762–771, doi:10.3762/bjnano.8.79
- nanostructure. Keywords: Au–DNA nanocomposites; enhanced fluorescence emission; metal-ion detection; Mg2+ ion detection; Introduction The interactions between Au nanoparticles (AuNPs) and DNA are essential to classify and expand upon, given the potential applications for NP–DNA complexes such as gene therapy
- idea about the electrostatic interactions between DNA and AuNPs. Metal-ion detection Upon excitation at 260 nm, the AuNPs did not exhibit fluorescence, however, bare herring sperm DNA used for detection showed fluorescence emission at 400 nm. A significant increase in the fluorescence emission (λex
- for analysis. The sample preparation and procedure are described in the section Metal-ion detection. Some samples with unknown concentration were also used to check the viability of this sensing process. It was observed from the calibration curve (summarized in Supporting Information File 1, Figure S4
Hydrophilic silver nanoparticles with tunable optical properties: application for the detection of heavy metals in water
Beilstein J. Nanotechnol. 2016, 7, 1654–1661, doi:10.3762/bjnano.7.157
- of the nanoparticles occurred. Metal ion detection We investigated the optical sensing properties of the AgNP-3MPS material via absorption spectroscopy. Each solution of AgNP-3MPS/ion was prepared in spectroscopic cuvettes that were carefully cleaned to avoid contamination. To a specific amount of
