We build sensors according to the fluorescent PET (photoinduced electron transfer) switching principle, which was first generalized by us. Some of these sensors have had sales of $540m so far in the hands of Optimedical Inc. and Idexx laboratories Inc.. We introduced molecular logic as a new experimental field. 



We have now begun to persuade molecules to emulate some information-processing tasks that we perform often, e.g. drawing the outline of a picture.
