Allows controlled attachment of nano-objects to be performed weeks apart in any lab

Scientists at Georgia Institute of Technology have developed a nanolithographic technique that can produce high-resolution patterns of at least three different chemicals on a single chip at writing speeds of up to one millimeter per second. The chemical nanopatterns can be tailor-designed with any desired shape and have been shown to be sufficiently stable so that they can be stored for weeks and then used elsewhere. The technique, known as Thermochemical Nanolithography is detailed in the December 2009 edition of the journal Advanced Functional Materials. The research has applications in a number of scientific fields from electronics to medicine.
