Via conjugating functional molecules onto magnetic nanoparticles, magnetic nanoparticles become useful for specifically labeling bio-entities such as proteins, viruses, cytokines, nuclei acids, or even chemicals.  This feature promotes the value of magnetic nanoparticles in applications of bio-medicines after bio-functionalizing magnetic nanoparticles.  The popular bio-medical applications of bio-functionalized magnetic nanoparticles are protein purification, cell sorting, MRI contrast medium, gene magnetofection, etc.  MagQu applies bio-functional magnetic nanoparticles to bio-molecules assay via immnomagnetic reduction technology, which is one of the core technologies of MagQu.

In order to keep a stable access to bio-functionalized magnetic nanoparticles, MagQu built up a manufacture line for synthesize magnetic nanoparticlesbio-functionalized with various bio-molecules, such as antibodies, proteins, single-strand DNA/RNA, or aptamers.  Through chemical reaction, bio-molecules are covalently bound with the hydrophilic layer of magnetic nanoparticles.  The high stability of bio-functionalized magnetic nanoparticles dispersed in PBS solution is evidenced with the particle size evolution during the storing period at 4 to 20 oC.  MagQu is supporting you to develop magnetic nanoparticles with new bio-functions for novel applications.
