Scientific Calendar Event

The Abdus Salam International Centre for Theoretical Physics (ICTP) is organizing a Regional Workshop on Optofluidics and Optical  to be held from 7 November to 11 November, 2011 at the University of Cape Coast, Ghana.

Optical manipulation implies the use of the radiation pressure of light on small samples immersed in liquid, gas or vacuum. Accordingly the technique is called optical tweezers (liquid) or optical levitation (gas or vacuum).  Advances in these areas have lead to very interesting application-driven research and technology development.  The goals of the workshop are to introduce the principles of optical manipulation, discuss in detail some of the multidisciplinary application areas of interest to West Africa, and to have participants run basic experiments under expert supervision.
The long-term goals are to foster a sustainable effort in the areas of biophysics and biomedicine in West Africa. Specifically, a major application in biophysics is the study of the mechanical properties of cells and of many types of motor molecules and other macromolecules responsible for the motion of organelles within cells and the locomotion of entire cells. Such studies can be initiated with the optical techniques covered by this workshop. 


•Fundamentals of optical manipulation: optical   tweezers and optical levitation.
•Fundamentals of micro-fluidics and phase optical microscopy
•Fundamentals of cell mechanics and molecular motors
•Research topics in optical manipulation and applications in life science.
•Experimental demonstrations of optical manipulation.
•Discussions on instrumentation development, and possible low cost – high impact   applications in physics and biomedicine. 


Scientists from all countries that are members of the United Nations, UNESCO or IAEA may attend the Workshop.  As it will be conducted in English, participants should have an adequate working knowledge of that language.  Although the main purpose of the Centre is to help researchers from developing nations through a programme of training activities within the framework of international cooperation, students and scientists from developed countries are also welcome to attend.  Travel and subsistence expenses of the participants should be borne by their home institution. There is no registration fee.
