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

    so, instead of trying to assembler individual atoms immediatelly, we learn to assemble particles a little bit bigger(an idea i’ve noted on my own much less plenty of those who are in a position to influence) which may be self-assembled nanoparticles(except maybe those spherical beads, the particle being moved didn’t look like a self-assembled nanoparticle); well, then your pretty close to atomically precise nanostructures.

    Now, if they can just use their holoassembler to combine and manipulate the self-assembled nanoparticles from the ‘precision nanoparticles’ guys in the article just below and maybe bring in some graphen and nanotubes . . .oh my . . . and, maybe some of those metalic oxides mentioned over at Drexler’s ‘metamodern’ website(been almost a year now; you might have to scroll for awhile!) to do some nano-chemistry . . . i don’t see how the dna-nanotech folks can be integrated with this holoassembler; well, Mr Pheonix talks about optical actuation of the dna-nanotech.

    Of the cameras that have been placed upon the backs of raptors, etc., has any camera yet been developed along the lines of your logo with a “viewpoint” from every angle, so that when fit together get 360 degrees of photos? That might be interesting for space, or for the earth as well.

    It’s an interesting concept, the complexity of a multi-camera in one defined space.
