Unrivaled Technical Expertise
Nanoparticles, with their unique size - dependent properties, have revolutionized fields such as materials science, pharmaceuticals, environmental science, and biotechnology. Precise characterization is essential to determine their size, shape, surface charge, chemical composition, and other critical parameters. Our service is designed to meet these diverse needs, leveraging state-of-the-art equipment and expert analysis.
Our Services
DLS is a powerful technique for determining the size distribution of nanoparticles in a liquid suspension. It measures the Brownian motion of particles, and from this, the hydrodynamic diameter is calculated. This method is highly effective for analyzing nanoparticles in the sub - nanometer to micrometer range, providing information on the average particle size and polydispersity. It is ideal for quickly assessing the stability of nanoparticle dispersions, as changes in size distribution can indicate aggregation.
Endotoxins are toxic substances found in the cell walls of gram - negative bacteria. In biomedical and pharmaceutical applications of nanoparticles, endotoxin contamination can lead to adverse effects. Our endotoxin testing service for nanoparticles ensures that your nanoparticle formulations are free from these harmful contaminants. Using sensitive detection methods, we accurately quantify endotoxin levels, helping you meet regulatory and safety requirements.
Inductively Coupled Plasma - Mass Spectrometry (ICP - MS) is a highly sensitive technique for analyzing the metal concentration in nanoparticle samples. It can detect a wide range of metals, including trace elements, with extremely low detection limits. This is crucial for applications where the metal content of nanoparticles needs to be precisely controlled, such as in semiconductor manufacturing, environmental monitoring of nanoparticle - metal interactions, and in biomedical applications where metal - based nanoparticles are used.
Scanning Electron Microscopy (SEM) provides high - resolution images of the surface morphology of nanoparticles. It allows you to visualize the shape, size, and surface features of nanoparticles. SEM can be used to analyze nanoparticles in a dry state, and with energy - dispersive X - ray spectroscopy (EDS) capabilities, it can also provide information on the elemental composition of nanoparticles. This technique is valuable for understanding the physical characteristics of nanoparticles that can impact their performance in various applications.
Transmission Electron Microscopy (TEM) offers even higher resolution than SEM, enabling detailed analysis of the internal structure of nanoparticles. It can reveal information about the crystal structure, defects, and core - shell architecture of nanoparticles. TEM is essential for applications where a deep understanding of the nanoscale structure is required, such as in the development of advanced nanomaterials for electronics and catalysis.
UV - Visible spectroscopy is used to analyze the optical properties of nanoparticles. The unique size - dependent optical absorption of nanoparticles, such as the surface plasmon resonance in metal nanoparticles, can be studied using this technique. It provides information on the concentration and size - related optical characteristics of nanoparticles, which is useful for applications in optoelectronics, sensing, and biomedical imaging where the optical properties play a key role.
Zeta potential is a measure of the surface charge of nanoparticles in a dispersion. Our zeta potential analysis service helps determine the stability of nanoparticle dispersions, as well as their interaction with other molecules. A high absolute value of zeta potential indicates good stability, as the charged particles repel each other. This is crucial for applications such as drug delivery, where the stability of nanoparticle formulations in biological fluids is essential.
