Introductions

The demand for materials with specific, enhanced magnetic properties is growing at an unprecedented rate. Modern applications require more than just standard magnets; they demand materials with precise coercivity, high remanence, superior thermal stability, tailored surface functionality, and resistance to harsh environments. Developing such materials requires a multidisciplinary approach, combining chemistry, physics, and materials science.CD Bioparticles was established to meet this complex challenge. We are a team of scientists and engineers dedicated to the design, synthesis, and optimization of advanced magnetic materials. We move beyond off-the-shelf products to deliver custom-engineered solutions that are precisely tailored to the unique performance requirements of your application, ensuring optimal functionality and reliability in your final product.

Technology Overview

Our capabilities are rooted in a deep understanding of magnetic phenomena and advanced material synthesis techniques. Our technological foundation encompasses:

Precision Synthesis: We utilize a wide array of methods, including co-precipitation, hydrothermal/solvothermal synthesis, thermal decomposition, sol-gel processes, and high-energy ball milling to achieve precise control over the size, shape, crystallinity, and magnetic properties of the materials we create.

Surface Engineering & Coating: A material's surface is its interface with the world. We specialize in applying sophisticated coatings—from inorganic layers like silica and precious metals to organic polymers and functional ligands—to enhance stability, prevent corrosion, reduce non-specific binding, and introduce specific chemical functionalities.

Advanced Functionalization: We covalently attach a vast library of biomolecules, polymers, and small molecules to our magnetic materials. This enables their use as targeted drug delivery vehicles, specific bioseparation agents, or highly sensitive diagnostic sensors.
