    =AFM manipulation=

    With AFM nanostructures such as nanotubes and nanowires lying on surfaces can be manipulated to create electrical circuits and admeasurement their automated backdrop and the armament complex in manipulating them.

    =STM manipulation=

    Using an STM alone atoms can be manipulated on surfaces to make breakthrough corals.

    =In-situ SEM manipulation=

    To adviser a three-dimensional nanomanipulation process, in-situ SEM or TEM abetment seems preferable. AFM (or STM) does accept the resolution to angel nanoscale objects, even down to the sub-atomic scale, but the imaging anatomy amount is usually apathetic compared to SEM or TEM and the structures will commonly accept to be planar. SEM offers the achievability of top anatomy rates; about nanometer resolution imaging of three-dimensional objects; imaging over a ample ambit of alive distances; and abounding surrounding aggregate in the sample alcove for the abetment setup. TEM has a abundant added bound amplitude accessible for the sample and abetment systems but can on the additional duke accommodate diminutive resolution. For abundant studies of the nanowires structure, TEM is a advantageous tool, but for the accumulation of nanoscale apparatus of a able-bodied authentic structure, such as accumulation bogus nanowires and nanotubes, the SEM resolution should be acceptable to complete the accumulation task.

    As the STM and AFM techniques opened up absolutely new fields of science by acceptance the investigator to collaborate with the sample rather than just observe, development of nanomanipulation accoutrement for SEM and TEM could apparently accept a agnate aftereffect for three-dimensional manipulation. Recently, bartering systems for such tasks accept become accessible such as the F100 Nanomanipulator Arrangement from Zyvex in October 2003. Several analysis groups accept aswell pursued developing such systems.

    To date the accoutrement acclimated for in-situ SEM nanomanipulation accept about alone been alone tips (AFM axle tips or categorical tungsten tips), sometimes tips acclimated calm with electron axle degradation accept been acclimated to make nanowire devices. Admitting the availability of bartering microfabricated grippers in the endure brace of years, little has been appear on the use of such accessories for administration nanostructures. Some electrical abstracts and abetment tasks accept been performed in ambient altitude with carbon nanotube nanotweezers.

    =In-situ TEM manipulation=

    TEM offers diminutive 3D resolution but the acute requirements on adherence accumulated with actual bound sample amplitude makes the contruction of in-situ TEM abetment accessories absolutely a task.

    With such systems, humans accept empiric advisedly abeyant affairs of alone atoms amid a gold tip and a gold surface; carbon nanotubes alive as nanoscale pipettes for metals and a abundance of additional alien phenomena.
