Unrivaled Technical Expertise
Carbon based nanoparticles, including carbon dots (CD), graphene quantum dots (GQD), fullerenes, carbon nanotubes (CNT), and nanodiamonds, have excellent performance combinations. Their high surface area, excellent conductivity and thermal conductivity, robust mechanical strength, and adjustable optical properties make them an ideal choice for a wide range of applications. However, standard ready-made options often fail to meet the precise requirements of specific projects. This is the advantage of our customized design services. We work closely with you to understand your exact specifications, from particle size and morphology to surface functionalization and biocompatibility, ensuring that the final product is fully suitable for your application.
Our Services
We offer a diverse range of carbon based nanoparticle combinations, each with unique characteristics suitable for specific applications
Carbon nanotubes (CNTs): single-walled (SWCNT) and multi walled (MWCNT) nanotubes with a length range of 50 nm to 50 μ m and a diameter range of 0.8 nm to 50 nm. single-walled carbon nanotubes have excellent conductivity and are an ideal choice for electronic products, while multi walled carbon nanotubes provide excellent mechanical reinforcement for composite materials.
Graphene and Graphene Oxide (GO): Single layer and few layer graphene sheets, as well as graphene oxide and reduced graphene oxide, with controllable oxygen content. Graphene has ultra-high thermal conductivity and mechanical strength, while GO provides hydrophilicity for biomedical applications.
Fullerenes: Spherical carbon cages (such as C60, C70) and embedded fullerenes (encapsulating atoms or molecules) are highly valued for their antioxidant properties and electron accepting ability.
Carbon quantum dots (CQDs): Fluorescent carbon nanoparticles (2-10nm) with adjustable emission spectra, providing low toxicity and high biocompatibility for imaging and sensing.
- Structure and size control
Accurate control over structure and dimensions is crucial for optimizing performance:
Length and diameter adjustment: For carbon nanotubes and graphene nanoribbons, the diameter tolerance of single-walled carbon nanotubes is precise to ± 0.5 nm, ensuring uniform electronic performance.
Layer control: For graphene, produce single-layer, double-layer, or few layer boards to regulate conductivity and mechanical properties.
Surface Area Optimization: High surface area porous carbon nanoparticles (such as activated carbon nanospheres) for adsorption and catalytic applications, with a surface area of up to 2500 square meters per gram.
Surface modification enhances compatibility, reactivity, and functionality:
Chemical functionalization: Covalent connection of functional groups (amines, carboxyl groups, hydroxyl groups) for biological coupling or polymer grafting, improving dispersibility in aqueous or organic matrices.
Non covalent coating: adsorption of polymers (such as PEG, chitosan) or biomolecules to enhance biocompatibility without altering their inherent properties.
Doping: Introducing heteroatoms (nitrogen, boron, phosphorus) to alter conductivity and catalytic activity is crucial for energy storage and conversion devices.
Metal nanoparticle decoration: Anchoring metal nanoparticles (Au, Pt, Fe) onto carbon surfaces to create hybrid materials for catalysis and sensing.
Technical Expertise and Comprehensive Methods
CD Bioparticles uses advanced synthesis techniques to produce high-quality carbon based nanoparticles:
- Chemical Vapor Deposition (CVD): Used to control the growth of carbon nanotubes and graphene, achieving precise control over length, diameter, and arrangement.
- Arc discharge and laser ablation: used for producing high-purity single-walled carbon nanotubes and fullerenes with minimal defects.
- Hydrothermal/solvothermal synthesis: CQD and porous carbon nanoparticles can be produced on a large scale using sustainable precursors such as biomass.
- Stripping method: Liquid phase and mechanical exfoliation for graphene production to ensure single-layer yield and minimal oxidation.
