Unrivaled Technical Expertise
Nanoparticles have received widespread attention in many fields due to their unique size dependent properties. The ability to accurately characterize its morphology, size, distribution, and surface features is crucial for understanding its performance and behavior. Scanning electron microscope (SEM) is a powerful imaging technique that uses a focused electron beam to scan the surface of a sample, generating high-resolution images. This technology allows for direct visualization of nanoparticles, providing detailed information about their shape, size, and surface morphology. At CD Bioparticles, we recognize the importance of precise nanoparticle analysis. Our SEM nanoparticle analysis service aims to meet the diverse needs of our customers. Whether you need to analyze the size distribution of nanoparticles in drug delivery systems, examine the surface morphology of electronic device nanomaterials, or study the aggregation behavior of nanoparticles in biological environments, our team has the expertise and equipment to provide accurate and meaningful results.
Our Services
Proper sample preparation is crucial for obtaining high-quality SEM images and reliable analysis results. We offer a range of sample preparation techniques for different types of nanoparticle samples:
- Dispersion optimization: For nanoparticle suspensions, we use specialized dispersion methods to prevent aggregation and ensure that individual nanoparticles are clearly visible in SEM images. This may involve ultrasonic treatment, use of appropriate dispersants, or optimization of pH values.
- Installation and coating: Based on the properties of the sample, we carefully install the nanoparticles onto a suitable substrate. For non-conductive samples, we apply thin conductive coatings (such as gold or carbon) to prevent charging effects during SEM imaging, otherwise the image will be distorted.
- Low temperature scanning electron microscopy preparation: For sensitive nanoparticles that may be damaged by traditional sample preparation methods (such as samples in aqueous solutions or biological samples), we provide low-temperature scanning electron microscopy formulations. This technology involves rapidly freezing samples to maintain their natural structure for accurate characterization.
We provide professional SEM nanoparticle analysis services, covering the following:
- Morphological analysis of nanoparticles: Obtaining information such as size, shape, and distribution of nanoparticles through SEM images helps researchers understand the physical properties of nanoparticles.
- Surface structure analysis: SEM can provide three-dimensional surface images of nanoparticles, revealing their surface microstructures such as cracks, pores, etc.
- Elemental composition analysis: Combined with EDS technology, elemental composition analysis can be performed on nanoparticles to determine their chemical composition.
- Sample preparation and optimization: We provide one-stop services from sample preparation to data analysis, including sample drying, coating, fixation, and other steps to ensure the accuracy of SEM analysis results.
- Customized analysis plan: Based on the specific needs of customers, provide customized SEM analysis plans, including settings for different magnifications and detection modes, to meet diverse research needs.
- Imaging and Characterization
Our advanced SEM systems provide high-resolution imaging and a wide range of characterization capabilities:
- Morphology Analysis: We capture high-quality images of nanoparticles to determine their shape (such as spherical, rod-like, cubic, or irregular), surface texture, and any structural features.
- Size Measurement and Distribution: Using specialized image analysis software, we measure the size of individual nanoparticles and generate size distribution data. This includes parameters such as average size, median size, and size range, providing a comprehensive overview of the nanoparticle population.
- Elemental Analysis (EDS): Equipped with Energy Dispersive X-ray Spectroscopy (EDS) detectors, our SEM systems can perform elemental analysis of nanoparticles. This allows us to identify the elemental composition of the nanoparticles and determine the distribution of elements within individual particles or across the sample.
- Aggregation and Dispersion Assessment: We evaluate the degree of aggregation or dispersion of nanoparticles, which is critical for understanding their behavior in different environments and applications.
