Abstract
Coccoid cells of the bacterial species Staphylococcus aureus have been mechanically trapped in lithographically patterned substrates and imaged under growth media using atomic force microscopy (AFM) in order to follow cellular processes. The cells are not perturbed as there is no chemical linkage to the surface. Confinement effects are minimized compared to trapping the cells in porous membranes or soft gels. S. aureus cells have been imaged undergoing cell division whilst trapped in the patterned substrates. Entrapment in lithographically patterned substrates provides a novel way for anchoring bacterial cells so that the AFM tip will not push the cells off during imaging, whilst allowing the bacteria to continue with cellular processes.Entities:
