Magnetic nanoparticles have emerged as a pivotal class of nanomaterials in modern scientific research, driven by their unique combination of nanoscale dimensions and magnetic responsiveness. Over the past few decades, advancements in nanotechnology have refined the synthesis and functionalization of these particles, expanding their applicability across multiple interdisciplinary fields.
The 200 nm size range of magnetic nanoparticles is specifically engineered to balance key performance attributes: sufficient magnetic moment for effective manipulation under external magnetic fields, and optimal biocompatibility for interactions with biological systems in research settings.
Unlike larger magnetic particles that may induce aggregation or cytotoxicity, and smaller nanoparticles that often exhibit weaker magnetic responsiveness, 200 nm magnetic nanoparticles strike a critical equilibrium that makes them versatile for academic and industrial research.
Fe₃O₄ (magnetite) is selected as the magnetic core due to its inherent superparamagnetic properties, high saturation magnetization, and low toxicity—traits that are indispensable for applications requiring precise magnetic control without permanent magnetization after field removal.
This product is developed exclusively for research purposes, supporting studies in areas such as materials science, biotechnology, biomedical engineering, and environmental science. It serves as a foundational tool for researchers exploring novel methodologies in separation, imaging, drug delivery systems, and catalytic processes.
Superparamagnetic behavior ensures rapid response to external magnetic fields and complete demagnetization once the field is removed, preventing particle aggregation and facilitating repeated use in experiments.
Highly uniform particle size distribution (targeting 200 nm) minimizes variability in experimental results, ensuring consistency across assays and replicable research outcomes.
High saturation magnetization (～55 emu/g) enables efficient magnetic separation and manipulation, reducing processing time in sample preparation and analysis workflows.
Excellent biocompatibility of the Fe₃O₄ core and sterile water preservation fluid eliminates unwanted biological interactions, making it suitable for in vitro cell studies and biological sample processing.
Sterile water as the preservation medium ensures no contamination of research samples, maintaining the integrity of experiments involving sensitive biological or chemical systems.
Stable storage at 2-8°C (with short-term room temperature stability) offers flexibility in laboratory handling and transportation, reducing logistical constraints for research teams.
Two-year shelf life provides long-term usability, allowing research labs to stock inventory without frequent replacement and supporting long-duration projects.
Superior magnetic responsiveness compared to smaller Fe₃O₄ nanoparticles, enabling more efficient separation and targeting in research applications such as cell sorting and magnetic resonance imaging (MRI) contrast enhancement.
Enhanced colloidal stability in aqueous environments due to optimized particle size and surface properties, preventing aggregation during storage and experimental use.
Non-toxic composition (Fe₃O₄ core and sterile water) eliminates safety concerns associated with toxic magnetic materials, ensuring compliance with laboratory safety standards for research use.
High concentration (100 mg/mL) reduces the volume of particles required per experiment, offering cost-effectiveness and minimizing waste in research workflows.
Versatile applicability across multiple research fields eliminates the need for specialized magnetic particles for different projects, simplifying laboratory inventory management.
Rigorous quality control during production ensures consistent performance batch-to-batch, reducing experimental variability and enhancing the reliability of research data.
Easy integration into existing laboratory protocols without the need for specialized equipment or complex modification, accelerating research progress and lowering operational barriers.
For research use only, not for clinical use.
