Title:
WATER-DISPERSIBLE MAGNETIC PARTICLE UTILIZING ELECTROSTATIC INTERACTION
Document Type and Number:
Japanese Patent JP2008069093
Kind Code:
A
Abstract:
To provide a simply handleable water-dispersible magnetic particle reducing nonspecific adsorption of a biological substance such as a protein and stably dispersible by utilizing stronger interaction of the particle with a dispersing agent.
