4D micro/nano scale particle tracking microscopy (Max Wasserman and Eugene Kalinin) It is known that bacteria's ability to communicate plays an important role in their ability to disperse, to lauch an attack to a host cell, or to form biofilms. We are interested in studying bacteria's collective dynamics when they are subjected to different chemical and nutrient environment. Our approach is to track positions of multiple swimming bacteria both in time and space. READ MORE. |

The 4D tracker (Max Wasserman)- an inhouse software packageAs we enter the era of quantitative biology, there is an immediate need for a new set of quantitative tools to probe the spatial and dynamical information of biological entities (such as bacterial cells, proteins) at micro and nano scales. We have developed imaging techniques that are able to track micron meter scale particles in all four dimensions (x,y,z,t) using a single CCD video camera. READ MORE. |
