Chromosome Nanomanipulation




Nanonics' systems can use any type of probe, but our unique glass probes are perfect for chromosome nanomanipulation and imaging. Glass probes do not only allow for the imaging of soft structures such as this human chromosome but are also ideal, because of their slender and extended shape, for the precise dissection of such structures.

Yeast Cells Fluorescence

Yeast Cells 
Zooming from Far-field to Near-field

Far-field optical images of yeast cells in a liquid cell 

X5 optical image   X10 optical image
X20 optical image   X50 image with the fiber probe in place illuminating the sample  
Nanometric scale images obtained without moving anything 
7x7micron AFM Topgraphy   NSOM GFP Fluorescence    NSOM Transmission

These three images show the same region of GFP labelled yeast cell in a physiological medium. The images were obtained simultaneously with the MultiView 1000 system integrated with a Nanonics dual microscope.


Only Nanonics' systems can zoom in on living samples from the far-field to NSOM producing images of such high quality.

The simultaneous imaging of a sample in both far- and near-fields, from above and below the sample can be achieved only by virtue of the Nanonics' free optical axis.

NSOM imaging of biological samples such as these is possible in the Nanonics liquid cell using optical fiber probes intermittant contact mode. Other NSOM techniques using hollow probes are limited in their ability to image in the intermittant contact mode.

Video of protein printing in real time

Only Nanonics can deliver chemicals or gas onto the sample on line, with no need to remove the tip from the sample.

Protein printing is made possible by the Nanonics Chemical Delivery System and Nanopipette


Using any of the Nanonics MultiView systems, chemicals, in liquid or gas form, can be fed into the pipette via a silicon tube. Apart from Protein Printing, applications of this setup include metallic nano-etching and nanolithography: an etchant can be introduced into the sample and scanned across it with nanometer precision using our 3D FlatScanning™ technology. The nanopipette is engaged by the sample using standard contact-mode atomic force microscopy, and our integrated system makes it possible to view the etching simultaneously through any optical microscope.

Neuronal Response to Caffeine Using a Chemical Probe in SPM 


Functional Calcium Imaging - An Optical Alternate to Patch Clamping


  • In this series of images a Nanopipette probe containing OrangeGreen is held in place with AFM control over a neuronal cell membrane of a cell which is filled with Fluo3.
  • The probe tip and the cell are excited in epi-illumination.
  • Each frame in the image is one confocal scan with 250 millisecond intervals between frames.  
  • A puff of caffeine is injected just before the fourth image (top row).
  • The cell and tip respond to the caffeine peaking in the center of the second row. Some of the pixels are red indicating that calcium has flowed out of the membrane and can be found at the tip which is in close proximity to the cell membrane.
  • Only Nanonics produces such probes for chemical imaging.

Fluorescence NSOM Images

35x35 micron AFM image    35x35 micron Transmission FluorescenceNSOM image

These images were produced using in the Intermittant Contact mode in a liquid environment using the Nanonics Liquid Cell with the MultiView 1000 system.


These topographic and fluorescence images were obtained simultaneously with cantilevered NSOM fiber optic probes. Labelled with rabbit anti-fibronectin primary antibody which was followed by a goat anti-rabbit Alexflour 488 secondary antibody. The Alexaflour probe is excited at about 488 and emits approximately 520nm. Thus, all fibronectin should be fluorescent. Fibronectin is part of the extracellular matrix which attaches the cell to the glass substrate.

The cell is visible in the AFM topography image but the fluorescent image shows mainly fibers. The fibers are primarily under the cell and therefore are difficult to image with AFM unless the cell is thin enough and these cells are thick since they were imaged at a more advanced stage in their growth. However, the fibers are fluorescent so they show up in the fluorescence NSOM optical image.
