Summary on Grant Application Form |
|
This is a visiting fellowship application to allow Prof G Spalding to visit and work with the St Andrews optical trapping group for a range of wholly new tweezing ideas. Prof. Spalding will be able to supply significant specialist equipment for this work. In combination with resources at St Andrews, this will enable new studies mainly in the field of multiple tweezers will be performed. Two major distinct themes wit be developed: the use of evanescent waves for optical tweezing. Mechanism for enhancing the tweezing forces and generating extended tweezing sites will be studies. -In addition experiments will be performed to look at the transfer of spin and orbital angular momentum to the trapped particles. In addition holographic tweezers using specially fabricated holograms (provided by Dr Spalding) will be used to embark on new work in colloid physics. This includes a study of laser induced freezing and studies of the how varying the orientation of the trap array relative to the external driving force results in a hierarchy of lock-in transitions. The ability of these multiple tweezer mechanisms to manipulate biological samples (chinese hamster chromosomes) will be investigated.
