Although transmission electron microscopy (TEM) may be one of the most efficient techniques available for studying morphological characteristics nanoparticles, analyzing them quantitatively in a statistical manner is exceedingly difficult. Herein, we report method mass-throughput analysis morphologies nanoparticles by applying genetic algorithm to an image technique. The proposed enables over 150,000 with high precision 99.75% and low false discovery rate 0.25%. Furthermore, clustered...
We demonstrate a strategy for the synthesis of discrete and uniform gold nanorod (GNR)@mesoporous silica (mSiO2) core–shell nanoparticles (NPs) with finely tuned shell thickness by significantly suppressing formation undesired core-free NPs. could control mSiO2 high precision, close to 1 nm, hence rotational diffusion mode NPs simply controlling precursor injection times. The growth on GNR seeds be explained two models based modified LaMer's theory. Between these two, we found most suitable...
Mesoporous silica nanoparticles (MSNPs) are well known for their adhesive properties with hydrogels and living tissues. However, achieving direct contact between the nanoparticle surface adherend necessitates removal of capping agents, which can lead to severe aggregation when exposed wet surfaces. This is ineffective simultaneously bridging two adherends, resulting in a reduced strength. In this study, we designed synthesized mesoporous nanochains (MSNCs) enhance interactions by promoting...
Here, we systematically investigated the independent, multiple, and synergic effects of three major components, namely, ascorbic acid (AA), seed, silver ions (Ag+), on characteristics gold nanorods (GNRs), i.e., longitudinal localized surface plasmon resonance (LSPR) peak position, shape, size, monodispersity. To quantitatively assess shape dimensions GNRs, used an automated transmission electron microscopy image analysis method using a MATLAB-based code developed in-house concept solidity,...
Abstract The ζ‐potential and hydrodynamic size ( d h ) of nanoparticles (NPs) are systematically controlled by capping gold NPs (AuNPs) with polymers having different charges treating them in NaCl solutions diverse concentrations. Interactions between AuNPs hydrogel caused chemical reactions induced 1,4‐dithiothreitol. effect is clear, as negatively charged can be aggregated neutral agarose gel, but the amount aggregation significantly affected magnitude negative surface charge on AuNPs....
Inversion of the role Au(<sc>iii</sc>) chloride allows facile synthesis smooth and spherical AuNPs with nanoscale size tunability.
The limited intragap distance tunability of clustering nanoparticles with different surface chemistries resulted in unwanted interference between embedded and restricted functionality. This leads to an urgent need for a new strategy that enables the assembly building block obtained from solvents polarities defined compositions, distances, orientations. Herein, we used organosilicasome (OSS), organic–inorganic hybrid compound covered surfactant, cluster diverse high configurational regardless...
Abstract DNA visualization has advanced across multiple microscopy platforms, albeit with limited progress in the identification of novel staining agents for electron (EM), notwithstanding its ability to furnish a broad magnification range and high‐resolution details observing molecules. Herein, non‐toxic, universal, simple method is proposed that uses gold nanoparticle‐tagged peptides stain all types naturally occurring molecules, enabling their under EM. This enhances current capabilities,...
Organosilicon compounds have been actively used with nano- and micro-fillers to improve the adhesion mechanical properties. However, studies on properties of polymeric materials, such as polypropylene (PP), functionalized organosilicon are limited. Here, we investigated organosilanized PP substrates, using (3-glycidoxypropyl)trimethoxysilane (GPTMS) (3-aminopropyl)trimethoxysilane (APTMS) coupling agents, epoxy adhesives. The curing epoxy-functionalized (PP-EPOXY) triethylenetetramine (TETA)...
Abstract We introduce Dual Optical Mapping (DOM), a method combining sequence-specific barcodes and AT frequency-dependent profiles. Conventional optical mapping primarily depends on generated by enzymes. There are also several profiling methods. However, these methods often face challenges, including reduced confidence due to large distances between labels, the occurrence of false positives negatives, issues single-molecule heterogeneity. Addressing limitations, we devised DOM, which...
In biological systems, a few sequence differences diversify the hybridization profile of nucleotides and enable quantitative control cellular metabolism in cooperative manner. this respect, information required for better understanding may not be each nucleotide sequence, but representative contained among them. Existing methodologies design have been optimized to track function genetic molecule predict interaction with others. However, there has no attempt extract new represent their...
