The Department of Electrical Engineering hereby invite all interested to a docent lecture in subject electrical engineering with specialization in Biological and Medical sensor technology.

Lecturer: Dr. Apurba Dev

Title:  Electrokinetic effect: Prospects for biomedical sensing

Date: Wednesday, 29^th January

Time: 10:15 AM

Location: 80101, Ångströmlaboratoriet, Lägerhyddsvägen 1, Polacksbacken

Chairperson: Professor Shi-Li Zhang

Representative of the Docentship Committee: Professor Thomas Edvinsson

Abstract: Electrokinetic effect such as streaming current/streaming potential is among the few methods that have been widely investigated for accurate understanding of particle deposition mechanism at the solid-liquid interface. The electrokinetic method allows real-time measurement of deposition kinetics as well as determination of surface coverage of particles with unprecedented precision. The method being a result of electrostatic and hydrodynamic interaction at the solid-liquid interface also allows for qualitative assessment of average size and zeta potential of the adsorbing particles.

In this lecture I shall discuss the prospects of the method as a sensitive detector for biological entities including small molecules (size < 5 nm), e.g. proteins, antibodies, affibodies, and large particles (size ~100 nm), such as extracellular vesicles. We shall also discuss the influence of particle size and zeta potential on the detection sensitivity using both theoretical and experimental approach.

The lecture is an obligatory teaching test for those applying for admittance as docent and it should be possible for students and others with basic academic education in the relevant field to follow it. The lecture will last for 45 minutes and afterwards the audience may ask questions. The lecture will be given in English.

Welcome!
