Dec 1, 2019 · Scanning electron microscopy (SEM) was used to confirm the production of AuNPs and examine the morphology of the obtained AuNPs. SEM images were acquired using a JSM-6610LVnx (Jeol, Tokyo, Japan) instrument that was equipped with an Aztec Energy (UK) integrated X-ray energy dispersive spectrometer (EDS) and a high-resolution CCD camera.

Aug 1, 2024 · AuNPs possess exceptional stability, low resistance, high conductivity, and extensive light interaction, making them well-suited for biological sensing applications. This literature study begins by examining different approaches for synthesizing AuNPs, including chemical, physical, and biological methods, before exploring their use as biosensors.

Jan 1, 2022 · AuNPs are synthesized using the extract of plant materials and microorganisms. Different analytical methods are used for the characterizations of AuNPs. AuNPs are involved for the detection of heavy metals and toxic substances. The biological substances are separated using gold nanoparticles.

Sep 5, 2014 · In the present work, STEM-in-SEM has been carefully optimized and used to study the uptake and subcellular distribution of citrate stabilized gold nanoparticles in gill samples from Ruditapes philippinarum upon in vitro exposure of gill explants (ex vivo) to the nanoparticles.

Jun 8, 2023 · In this study, gold nanoparticles (AuNPs) were synthesized using the Turkevich method. This article explains the didactic step-by-step synthesis, showing pictures of the entire process, including a well-explained mechanism and characterization study.

Apr 5, 2019 · Gold nanoparticles (AuNPs) decorated CNTs are promising materials for photocatalytics and biosensors. However, the synthesis of AuNPs chemically linked to the walls of MWCNTs is challenging and...

Nov 23, 2022 · Here, we report a universal strategy to vastly enrich the library of nanoparticle superlattices, based on multiple-unit (≥4 units) DNA origami platforms, which were constructed by programmably cocrystallizing three different DNA origami octahedral “homologs.”

SEM image shows the spherical shape of the nanoparticles with a narrow size distribution of 52 ± 5 nm. Analytical centrifugation and SAXS analysis additionally confirmed the average diameter and...

Feb 12, 2025 · The green synthesis approach using extracts from cardamom seeds and pods facilitated the production of spherical AuNPs, confirmed by UV-vis spectroscopy, SEM, TEM, XRD, EDX and FTIR analysis.

The SEM analysis shows a good dispersion of AuNPs on the TiO 2 surface, which is an important feature required to obtain the optimal particle number to performance ratio.
