Magnetic nano-tags for molecules TurboBeads of Zurich, Switzerland, have launched covalently functionalised metallic cobalt nano-magnets to which organic and biological molecules can be linked with high ligand loading (up to 0.2mmol/g). These nano-beads with particle size below 50nm permit separation of tagged molecules or reagents after synthesis within seconds using low-cost commercial magnets. The beads are thermostable up to 190 ° C and are chemically inert in solvents and water at a wide rang of pHs.The beads can be applied in organic chemistry, biotechnology and medical diagnostics as an alternative to chromatography or crystallisation, and can be combined with automated sample handling. info@turbobeads.com http://www.rsc.org/chemistryworl ... ber/NewOnMarket.asp |
