In the dynamic fields of biotechnology, pharmaceuticals, and diagnostics, the one-size-fits-all approach often falls short. Achieving breakthrough results requires materials that are precisely tailored to your specific experimental conditions, assay parameters, and performance goals. CD Bioparticles provides expert Custom Magnetic Nanoparticle Services, dedicated to designing, synthesizing, and functionalizing magnetic nanoparticles to your exact specifications. We partner with you to overcome the limitations of off-the-shelf products, delivering nanoscale tools that enhance sensitivity, improve efficiency, and drive innovation in your applications.
Introductions
Magnetic nanoparticles are powerful tools for separation, detection, and analysis. However, standard particles can lead to suboptimal outcomes due to issues like non-specific binding, insufficient magnetic responsiveness, poor stability, or inadequate surface functionality for your unique target. The success of sophisticated protocols—from isolating rare cell populations to developing next-generation point-of-care diagnostics—hinges on the precise properties of the magnetic beads used. CD Bioparticles bridges this gap. We are not merely a manufacturer; we are your strategic R&D partner. Our service is built on a foundation of advanced chemistry and materials science, focused on creating proprietary magnetic nanoparticles that give you a competitive edge.
Technology Overview
Our custom synthesis leverages state-of-the-art technology and deep scientific expertise to control every aspect of the nanoparticle. Our core technological capabilities include:
Core Composition: Iron oxide (FeO₄, γ-Fe₂O₃) is standard, but we also work with doped ferrites and alloy cores to tune magnetic moment and chemical stability.
Size and Monodispersity: We can tailor particle diameters from as small as 5 nm up to several hundred nanometers with a very narrow size distribution (PDI < 0.1), ensuring consistent and predictable behavior.
Crystallinity and Morphology: Controlling the crystal structure and shape (spherical, cubic, core-shell) to optimize magnetic properties and surface area.
Our Services
Our custom service is a collaborative, iterative process designed to deliver exactly what you need.
Consultation and Requirement Analysis: We begin by deeply understanding your application, target molecule, buffer conditions, and performance criteria (e.g., binding capacity, capture kinetics, elution efficiency).
Design and Proposal: Our scientific team proposes a detailed material specification, including core size, coating matrix, and functional group, along with a project timeline and quote.
Synthesis and Prototyping: We develop an initial batch of custom nanoparticles, rigorously adhering to the agreed-upon specifications.
Comprehensive Characterization and QA/QC: Every batch undergoes stringent analysis before delivery. We provide a comprehensive report including:
- Physicochemical Data: Hydrodynamic size (DLS), zeta potential, concentration.
- Magnetic Properties: Saturation magnetization and coercivity (VSM).
- Functional Validation: Confirmation of ligand density and activity (e.g., HPLC, BCA assay, activity tests).
- Scale-Up and Ongoing Supply: Once the prototype is validated, we seamlessly scale production to meet your needs for R&D, clinical trials, or commercial product manufacturing, ensuring batch-to-batch consistency.
Applications
Our custom magnetic nanoparticles are engineered for a vast range of high-value applications:
- Diagnostic Assay Development: Creating highly sensitive and specific capture beads for lateral flow assays, automated immunoassays, and biosensors.
- Nucleic Acid Purification: Designing particles optimized for binding and releasing high-purity DNA/RNA from challenging sample types for NGS and PCR.
- Cell Isolation and Therapy: Developing beads for the positive or negative selection of specific cell types (e.g., CD4+ T cells, stem cells, CAR-T cells) with high viability and purity.
