Environmental pollution poses significant threats to ecosystems and human health worldwide. The accurate detection and monitoring of pollutants—including heavy metals, organic contaminants, and pathogenic microorganisms—are critical steps in addressing these challenges. However, traditional detection methods often suffer from limitations such as low sensitivity, long processing times, and poor performance in complex matrices.

Overview
CD Bioparticles is at the forefront of addressing these challenges with our advanced pollutant detection magnetic bead service. We specialize in designing and providing functionalized magnetic beads that enable highly efficient separation, concentration, and analysis of diverse pollutants. Our innovative solutions leverage the unique properties of magnetic nanoparticles, such as superparamagnetism, high surface-area-to-volume ratios, and versatile surface chemistry, to deliver detection services that are not only accurate but also time- and cost-effective. Our services are tailored to support a wide range of environmental monitoring applications, empowering industries and research institutions to make data-driven decisions for environmental protection and public health safety.
Our Services
CD Bioparticles' pollutant detection magnetic bead service is designed to be flexible, customizable, and end-to-end, catering to the diverse needs of clients across industries. Our service portfolio encompasses four core components, ensuring a seamless experience from project initiation to result delivery:
Customized Magnetic Bead Development
We understand that different pollutants require specific binding strategies. Our team of material scientists and biotechnologists works closely with clients to design and synthesize functionalized magnetic beads tailored to their target pollutants. This includes:
- Selection of magnetic bead core material and size (optimized for maximum binding capacity and efficient separation).
- Conjugation of target-specific ligands: antibodies (for microbial contaminants or large organic pollutants), aptamers (for small molecules like pesticides), chelating agents, or molecularly imprinted polymers (MIPs) for high selectivity in complex matrices.
- Quality control (QC) of functionalized beads: testing binding efficiency, specificity, and stability via techniques such as flow cytometry, UV-Vis spectroscopy, and magnetic separation efficiency assays.
End-to-End Pollutant Detection Assay Execution
For clients seeking turnkey detection solutions, we offer full assay execution, covering:
- Sample pretreatment: Optimization of sample extraction (e.g., liquid-liquid extraction for organic pollutants, acid digestion for heavy metals in soil) and cleanup to minimize matrix interference.
- Magnetic bead-based capture and enrichment: Implementation of the bead-pollutant binding protocol, including incubation time, temperature, and buffer conditions, followed by magnetic separation and elution of captured pollutants.
- Detection and quantification: Integration with complementary detection techniques (e.g., HPLC, GC-MS, inductively coupled plasma-mass spectrometry (ICP-MS), or lateral flow immunoassays (LFIA)) for accurate quantification of pollutants. We provide detailed analytical reports including standard curves, limit of detection (LOD), limit of quantification (LOQ), and reproducibility data.
Applications
The services of CD Bioparticles are adept at tackling a broad spectrum of environmental pollutants:
Heavy Metal Detection: Our DNAzyme-based magnetic beads can sensitively and selectively detect toxic heavy metal ions like UO₂²⁺ (uranium), Pb²⁺ (lead), Cd²⁺ (cadmium), and Hg²⁺ (mercury) in aqueous environments. The combination of specific molecular recognition and magnetic separation ensures accurate results even in complex water samples.
Organic Pollutant Monitoring: We utilize magnetic beads coated with adsorbent materials like β-cyclodextrin polymers to efficiently capture and concentrate persistent organic pollutants (POPs), pesticides, and polycyclic aromatic hydrocarbons (PAHs) from water and soil. This enrichment enables ultrasensitive detection using techniques like SERS or UV-Vis
