Nanoparticles & Beads Conjugation
Service Description
Relying on our state-of-the-art chemical biology facilities and years of combined experience in providing high-quality bioconjugate complexes, BOC Sciences is capable of conjugating a wide range of different biomolecules with nanoparticles and beads. We use the highest quality nanoparticles and beads when applying our proprietary conjugation protocols to provide optimized products and meet your assay needs. Specificity, sensitivity, and reproducibility are defined to meet your absolute expectations for conjugates.
What are Nanoparticles & Beads?
Nanoparticles are manufactured microscopic particles with sizes up to 100 nm. Semiconductor nanoparticles smaller than 10 nm are also known as quantum dots due to their quantized electronic energy levels. Nanoparticles may be in the form of emulsions, polymers, ceramic particles, metal particles, and carbon particles. Moreover, nanoparticles are of great scientific research value, bridging the gap between large pieces of matter and atoms and molecules. The physical properties of large pieces of matter are usually independent of size, but this is not the case at the nanometer size, and liposomes are typical nanoparticles with solid-like properties.

Beads are superparamagnetic microspheres with fine particle size. They can gather rapidly in a magnetic field and disperse uniformly when they lead the field contributing to magnetic separation. Some applications of beads include conjugating to drugs, proteins, enzymes, antibodies, or nucleic acids.
