Abstract
Modified diamond particles for use in chromatography with a desired functional group at the diamond surface, formed from reaction of hydroxyl groups at diamond surfaces with a reactive molecule.
Claims9
A diamond particle with a modified surface comprising:
- a plurality of bonding sites;
- and
- a plurality of straight chain alkyl molecules tethered to the diamond surface through urethane linkages at the plurality of bonding sites, wherein the plurality of straight chain alkyl molecules provide hindrance from further bonding reactions near the bonding sites.
A diamond particle with a modified surface comprising:
- a plurality of bonding sites;
- and
- a plurality of octadecyl isocyanate molecules tethered to the diamond surface through urethane linkages at a plurality of bonding sites, wherein the octadecyl isocyanate molecules provide hindrance from further bonding reactions near the bonding sites.
