Magnetic bioassays using functionalized magnetic nanoparticle

Assoc. Prof. Alexei Kalaboukhov

Chalmers University of Technology, Sweden

There has been an increasing interest in biological assays using magnetic nanoparticles coated with bio-molecule markers, such as antibodies or antigens. A new technique based on detection of Brownian relaxation time of magnetic nanoparticles has been developed that has several orders higher sensitivity as compared with enzyme-linked immunosorbent assay (ELISA). There is also a parallel development within the biotechnology area where the magnetic nanoparticles have been refined and specialized for specific tasks both for biological assays, hyperthermia, and for targeted drugs delivery. Microelectromechanical systems (MEMS) are being developed into lab-on-a-chip, containing microfluidic systems simplifying the transport, handling and analysis of the reagents under investigation. In this lecture, basic principles of magnetic bioassays will be discussed in view of potential applications in bio-diagnostics.

Brief Bio:

A. Kalabukhov was born in Moscow, Russia, in 1975. He received the MSc and Ph.D. degrees in physics and mathematics from Moscow State University in 1998 and 2003, correspondingly. Since 2003, he is with Quantum Device Physics Laboratory at the Department of Microtechnology and Nanoscience – MC2, Chalmers University of Technology, Göteberg, Sweden. His main research interest is in bio-magnetic applications of high-TC SQUIDs. He is also actively involved in emerging field of functional oxide interfaces and oxide electronics. He is teaching several courses in superconductivity, superconducting electronics, and nanoscience at Chalmers University of Technology.
