Carrier Polymer Particle, Process for Producing the Same, Magnetic Particle for Specific Trapping, and Process for Producing the Same

A process for producing carrier polymer particles comprising covering the surface of organic polymer particles having a particle diameter of 0.1 to 20 micrometers with a saccharide by chemically bonding the organic polymers and the saccharide.

A process for producing carrier polymer particles comprising:

• covering organic polymer particles with a particle diameter of 0.1 to 20 micrometers, which has a functional group having reactivity with a carboxyl group, with a saccharide having a carboxyl group by chemically bonding the organic polymer particles and the saccharide, and
• treating the organic polymer particles, of which the surface has been covered with the saccharide, with a basic solution.

Magnetic particles for specific trapping comprising:

• magnetic particles having a particle diameter of 0.1 to 20 micrometers and a saccharide, the magnetic particles and the saccharide being chemically bonded, and
• a probe for specifically trapping a target material being bonded to the saccharide.

A process for producing the magnetic particles for specific trapping comprising:

• chemically bonding magnetic particles having a diameter of 0.1 to 20 micrometers to a saccharide and
• chemically bonding a probe for specifically trapping the target material to a saccharide.
