Title: High-speed AFM meets the Holographic Assembler

Mervyn Miles

Bristol University

Abstract: High-speed AFM is important for following processes occurring on short time scales inaccessible to conventional AFM. We are working on two versions: one is capable of extremely high imaging rates and can image over relatively large areas on samples with relatively large height variations, and the other is a noncontact version which is more appropriate for studying single molecular bio processes in liquid. Both are also capable of writing structure,s e.g., by electrochemical oxidation, at high-speed. The majority of our examples are biological. At the same time, we have been developing a holographic optical tweezers instrument capable of assembling, sometimes automatically, structures which go from individual nanotools to photonic bandgap crystals. The nanotools can be used, e.g., to manipulate living cells or can become an independent AFM probes operating with all degrees of freedom (see http://HoloAssembler.com). We are now interfacing to both of these instruments via a multitouch table which greatly increases their versatility and accessibility to the non-expert user. (Emphasis added)

The holographic assembler site states, “The dynamic holographic assembler (DHA) is being developed principally as a new technology for the assembly of functional devices using components from the micrometer scale to the tens of nanometers scale.”

Sounds interesting!  But note that the term Assembler here is used differently from the way Foresight uses it.  —Chris Peterson
