Unrivaled Technical Expertise
Metal nanoparticles are highly valued for their unique physical and chemical properties, including tunable optical properties, high specific surface area, excellent conductivity, and catalytic activity. Although there are various standard products to choose from, achieving optimal performance typically requires materials with highly specific properties, such as precise size distribution, tailored surface chemistry, and unique core-shell structures. Our customized design services aim to meet these strict requirements and transform your project from a concept to a successful reality.
Our Services
- Gold Nanoparticles (AuNP)
Gold nanoparticles are renowned for their excellent biocompatibility, surface plasmon resonance (SPR) effects, and chemical stability - properties that make them indispensable in biomedical and analytical applications. Our customization options include:
Size and shape control: Synthesize spherical, rod-shaped (nanorod), triangular (nanoplate), and star shaped (nanostar) gold nanoparticles with diameters ranging from 5 nm to 200 nm. Size adjustment directly regulates SPR absorption, and smaller particles (5-30nm) exhibit a color change from red to purple, allowing for visual monitoring of the reaction.
Surface functionalization: Coating with thiol terminated molecules (such as PEG, DNA, antibodies) to improve stability, biocompatibility, and targeting ability. Carboxyl or amine functionalization facilitates binding with biomolecules for biosensing and drug delivery.
Optical property adjustment: Optimize SPR peak (500-1000 nm) for applications such as colorimetric sensors, surface enhanced Raman spectroscopy (SERS) substrates, and photothermal therapy agents.
- Silver nanoparticles (AgNP)
Silver nanoparticles are renowned for their broad-spectrum antibacterial activity and excellent conductivity, making them an ideal choice for medical, consumer, and electronic applications. Our customization includes:
Size and morphology: spherical AgNPs (1-100nm), nanowires, and nanosheets with controllable aspect ratios. Smaller particles (1-20 nm) enhance the antibacterial effect, while nanowires (1-5 μ m in length) increase the conductivity of flexible electronic products.
Surface coating: PVP or chitosan coating can prevent aggregation and enhance dispersibility in aqueous or organic matrices. Biocompatible coatings can ensure the safe use of medical devices and food packaging.
Stability enhancement: Optimize pH value and ion strength tolerance to maintain activity in harsh environments, such as industrial water treatment or physiological fluids.
Iron nanoparticles (FeNP)
Iron nanoparticles, including zero valent iron (nZVI) and iron oxide nanoparticles (such as magnetite and ferric oxide), provide unique reducibility and magnetism for environmental and biomedical applications. Our customization options include:
Type and phase control: synthesis of nZVI (50-500nm) for environmental remediation, and synthesis of iron oxide nanoparticles (5-100nm) with controlled phases (magnetite, magnetite) for magnetic resonance imaging (MRI) and targeted delivery.
Surface modification: Silicon dioxide or polymer coating to prevent oxidation of nZVI and prolong the reactivity of pollutant degradation. Amine or carboxyl functionalization of iron oxide nanoparticles for binding with targeted ligands.
Magnetic tuning: Adjusting the saturation magnetization and coercivity to optimize the performance of magnetic separation, hyperthermia, and MRI contrast enhancement.
Copper nanoparticles (CuNP)
Copper nanoparticles combine low cost with high catalytic activity and antibacterial performance, making them suitable for industrial catalysis, coatings, and energy storage. Our customization includes:
Size and dispersion: Spherical CuNPs (10-200nm) with narrow size distribution ensure uniform catalytic activity. Use organic ligands for surface passivation to prevent oxidation in air.
Shape engineering: Nanocubes and nanowires used to enhance catalytic performance in reactions such as CO oxidation and water splitting.
Composite material formation: Combining with polymers or ceramics to manufacture antibacterial coatings for textiles and medical devices, or as conductive additives in lithium-ion battery electrodes.
Technical Expertise and Comprehensive Methods
CD Bioparticles use advanced synthesis techniques to produce high-quality metal nanoparticles and precisely control their properties
- Chemical reduction: water-based synthesis using reducing agents (such as sodium citrate for gold nanoparticles and borohydride for silver nanoparticles) to achieve uniform size and shape.
- Thermal decomposition: High temperature synthesis of iron oxide nanoparticles with controllable phase and crystallinity.
- Electrochemical synthesis: Used for producing high-purity and highly conductive copper nanoparticles.
- Sputtering and laser ablation: Physical methods that produce nanoparticles with minimal chemical pollution, making them ideal choices for biomedical applications.
Our representational capability ensures rigorous quality assessment:
- Dynamic Light Scattering (DLS): Determine size distribution and zeta potential (surface charge).
- UV visible spectroscopy: used to monitor SPR peaks (AuNP, AgNP) and optical properties.
- X-ray diffraction (XRD): used for crystal structure and phase identification (such as iron oxide).
- Antibacterial analysis: MIC (minimum inhibitory concentration) testing of AgNP and CuNP.
- Magnetic Performance Measurement System (MPMS): Used to evaluate the magnetization strength of iron nanoparticles.
