Why Choose Carbon Based Nanoparticles?

Our Carbon-Based Nanoparticles Design Service encompasses end-to-end solutions for the development of tailored carbon nanostructures, from material selection to scalable production. We specialize in engineering nanoparticles with controlled properties such as dimensions, surface chemistry, conductivity, and functional groups, ensuring optimal performance for target applications. Whether you require single-walled carbon nanotubes for high-strength composites, graphene quantum dots for bioimaging, or functionalized fullerenes for drug delivery, our service is designed to address your unique needs. By combining advanced synthesis techniques with rigorous characterization, we deliver carbon-based nanoparticles that adhere to the highest standards of quality and consistency.

Our Services

We offer a comprehensive portfolio of carbon-based nanoparticles, each with distinct properties for specialized applications:

• Carbon Nanotubes (CNTs): Single-walled (SWCNTs) and multi-walled (MWCNTs) nanotubes, available in lengths ranging from 50 nm to 50 μm and diameters from 0.8 nm to 50 nm. SWCNTs exhibit exceptional electrical conductivity (up to 10⁶ S/m) and mechanical strength (tensile strength ~130 GPa), ideal for electronics and high-performance composites. MWCNTs, with their concentric cylindrical structure, provide superior thermal stability and are widely used in energy storage and catalyst support.
• Graphene and Derivatives: Monolayer, bilayer, and few-layer graphene sheets, as well as graphene oxide (GO) and reduced graphene oxide (rGO). Graphene, a single layer of sp²-bonded carbon atoms, offers ultra-high thermal conductivity (~5000 W/mK) and mechanical flexibility, making it suitable for flexible electronics and thermal management. GO, with its oxygen-containing functional groups, provides hydrophilicity for biomedical applications, while rGO balances conductivity and processability for energy devices.
• Fullerenes: Spherical carbon cages (e.g., C60, C70) and endohedral fullerenes (encapsulating atoms or molecules). These nanostructures exhibit unique electron-accepting properties and antioxidant activity, used in organic photovoltaics, drug delivery, and as radical scavengers in cosmetics.
• Carbon Quantum Dots (CQDs): Fluorescent carbon nanoparticles (2–10 nm) with tunable emission spectra (350–700 nm) and low cytotoxicity. CQDs offer advantages over traditional quantum dots, including high biocompatibility and ease of surface functionalization, making them ideal for bioimaging, sensing, and optoelectronics.

Structural and Dimensional Control

Precise control over structure and dimensions is critical for optimizing performance:

• Length and Diameter Tuning: For CNTs and graphene nanoribbons, with diameter tolerances as tight as ±0.5 nm for SWCNTs to ensure uniform electronic properties. Length control (from nanometers to micrometers) enables customization for specific composite reinforcement or device architecture needs.
• Layer Control: For graphene, production of monolayer (thickness ~0.34 nm), bilayer, or few-layer sheets to modulate conductivity and mechanical properties. Monolayer graphene maximizes electrical performance, while few-layer graphene balances cost and functionality in composites.
• Porosity Engineering: Synthesis of porous carbon nanoparticles (e.g., activated carbon nanospheres) with controlled pore size (micropores <2 nm, mesopores 2–50 nm) and surface area (up to 3000 m²/g) for adsorption, catalysis, and energy storage applications.

Surface Functionalization

Surface modification enhances compatibility, reactivity, and functionality:

• Covalent Functionalization: Attachment of functional groups (amine, carboxyl, hydroxyl, thiol) via chemical reactions (e.g., diazonium coupling, epoxy ring opening) to enable bioconjugation or polymer grafting. This improves dispersion in aqueous or organic matrices and facilitates targeted interactions.
• Non-Covalent Coating: Adsorption of polymers (e.g., PEG, chitosan), surfactants, or biomolecules (proteins, DNA) to enhance biocompatibility without altering intrinsic properties. This is particularly valuable for CNTs and graphene used in biomedical applications.
• Doping: Introduction of heteroatoms (nitrogen, boron, phosphorus) to modify electrical conductivity and catalytic activity. Nitrogen-doped graphene, for example, exhibits enhanced ORR (oxygen reduction reaction) activity, critical for fuel cell applications.
• Hybridization: Decoration with metal nanoparticles (Au, Pt, Fe₃O₄) or semiconductor quantum dots to create multifunctional hybrid materials for catalysis, sensing, and theranostics.

Technical Expertise and Synthesis Methods

CD Bioparticles employs advanced synthesis techniques to produce high-quality carbon-based nanoparticles:

• Chemical Vapor Deposition (CVD): For controlled growth of CNTs and graphene, enabling precise control over length, diameter, and alignment. CVD-grown graphene offers high crystallinity and large domain sizes, ideal for electronic applications.
• Arc Discharge and Laser Ablation: For producing high-purity SWCNTs and fullerenes with minimal defects. These physical methods yield materials with exceptional structural integrity, suitable for fundamental research and high-performance devices.
• Hydrothermal/Solvothermal Synthesis: For scalable production of CQDs and porous carbon nanoparticles using sustainable precursors (e.g., biomass, carbohydrates). This green chemistry approach reduces environmental impact and enables cost-effective manufacturing.
• Exfoliation Methods: Liquid-phase exfoliation (using solvents or surfactants) and mechanical exfoliation for graphene production, ensuring high monolayer yield and processability.

Application-Specific Design

• Our expertise extends to designing carbon nanoparticles for specific applications. We have a proven track record of developing custom solutions for:
• Biomedical Applications: Design of biocompatible carbon dots for cell imaging, targeted drug delivery using functionalized graphene, and biosensors for disease detection.
• Energy Storage: Tailored carbon nanotubes and graphene for high-performance supercapacitors and lithium-ion batteries.
• Environmental Science: Development of advanced catalysts and adsorbents for water purification and environmental remediation.
• Electronics and Photonics: Custom-designed carbon materials for flexible electronics, transparent conductors, and optoelectronic devices.
• Materials Science: Creation of nanocomposites with enhanced mechanical and thermal properties.
