AFM Vibration Isolation Solution: Active Vibration Table

Atomic Force Microscopes which are quite susceptible to external vibrations, are able to measure topographic images at resolutions below 0.1 nanometers. The external vibrations need to be reduced in order to obtain the highest-quality AFM images, particularly for high-resolution scanning.

Both acoustic and and structural vibrations degrade the resolution and overall performance of Atomic Force Microscopy Instrumentation. The acoustic vibrations can be reduced by placing the microscope in an acoustic isolation chamber. On the other hand, structural vibrations can be reduced by using a mechanical isolation platform such as an active vibration table.

The vibration isolation tables are designed to provide stable working conditions for devices that are sensitive to vibration and shocks. The table consists of an outer table frame that supports the main work surface which is not isolated from vibration and an inner table frame that is entirely separate and supports the inner isolated work surface. This ensures vibrations are not transmitted to the isolated inner work surface. An Active Vibration Table uses a feedback control method for removing vibrations. An acceleration sensor measures vibrations and then electromechanical transducers use the output of the sensors to control the motion of the tabletop.

The advantage of an Active Vibration Table over the Bungee option is that the Vibration Isolation Tabletop is more stable than a platform suspended with bungee cords. Other equipment that provide vibration isolation include vibration enclosures, bungee options, and custom/OEM enclosures.

This being said, bungee solutions are often better for structural vibration reduction than active vibration tables.

How to Reduce External Vibrations

Acoustic and structural vibrations affect the resolution and overall performance of an Atomic Force Microscope. External vibration can degrade the resolution of scans by adding extra noise. Even though AFMs are quite susceptible to external vibrations, they can measure topographic data at resolutions below 0.1 nanometers in a normal laboratory environement.

Atomic force microscope vibration solutions offer a way to reduce external vibration that often causes fuzzy AFM images. To reduce external vibrations and obtain the highest-quality AFM images, particularly for high-resolution scanning, AFMWorkshop has designed a variety of proven options for vibration isolation including vibration tables, vibration enclosures, bungee options, and even custom/OEM enclosures. Vibration Isolation solutions filter out unwanted acoustic and structural vibrations that interfere with high-resolution scanning.

Acoustic vibrations are reduced by placing the microscope in an acoustic isolation chamber. Structural vibrations are reduced by using a mechanical isolation platform.

Have a look at the vibration solution products offered by AFMWorkshop:

Bungee Option

Bungee Option is a relatively cost-effective method for reducing unwanted structural vibrations and improving the quality of AFM Image.

The Bungee Option is used in the Acoustic Enclosure. Such combination allows a comparatively cost-effective way reducing structural mechanical vibrations and Acoustical noises and obtaining better quality AFM images.

Passive Vibration Table

Passive Vibration Table is moderate Vibration solution when ultimate AFM Performance is not necessary.

Active Vibration Table

An Active Vibration Table uses a feedback control method for removing vibrations for a better quality of scans.

Vibration Cabinet

Vibration isolation is essential for high-resolution AFM scanning. Vibrations from buildings, tables, and external vibration can affect the resolution of scans by adding extra noise. To further reduce vibration, it is recommended a vibration isolation cabinet.

Custom OEM vibration enclosure

Customized (OEM) Vibration enclosure is a scalable vibration solution for any Atomic Force Microscopy System.

Which AFM is best to Create New Instrumentation?

The TT-2 AFM is ideal for instrument builders that want to use an Atomic Force Microscope as a platform for creating new instrumentation (such as a new imaging mode), or who want to use an Atomic Force Microscope in combination with another analytical instrument.

Now, instrument innovators no longer have to face the decision to either create an entirely new AFM or to live with the limitations of commercial AFMs that have limited documentation and closed architecture.

Why choose TT-2 AFM?

TT-2 AFM software was developed in LabVIEW, making it easy for customers with a LabVIEW user license to customize their software. Therefore, TT-2 AFM customers have access to the systems software, mechanical drawings, and schematics.

TT-2 AFM was created in AutoCAD and is included in the optional documentation package. Single parts in the microscope can be purchased if you need to modify a part for your needs. All parts are identified by part numbers on each mechanical drawing.

LabVIEW software screen for AFM

National Instrument’s LabVIEW instrumentation programming language is setting the standard as the graphical programming environment for developing instrumentation. The instrument control protocol for addressing functions such as Z feedback, XY scanning, and stepper motor control is included with the technical documentation package. The AFMWorkshop does not provide a LabVIEW software development license – this must be purchased from NI.

The technical guide is available for developers that include schematics to all electronics in the TT-2 AFM including photodetector board, piezoelectric control board, controller mainboard, and even the power supply board.

How to Make Measurements on Biological Samples

When it comes to making measurements on biological samples at the nanoscale, Atomic force microscopes are used. In both ambient atmospheric conditions as well as liquid environments, AFM allows the nanoscale imaging of soft biomaterials including cells and DNA.

Have a look at the biology applications, unique to atomic force microscopes:

Double-stranded DNA Molecules

Imaging of DNA of size 5 µm x 5 µm can be done easily. Imaging of oligonucleotides can be used in a wide variety of applications, notably in structural studies, and in the study of interactions between the oligonucleotides and other molecules, such as enzymes.

Tobacco Mosaic Virus (TMV)

Imaging of Tobacco Mosaic Virus is commonly carried out in structural studies. Such high-resolution imaging requires an instrument noise floor of less than 0.1nm, a good tip approach leading to the maintenance of a sharp tip, the capability to scan with very light forces and placement of the microscope in an environment with minimal structural and acoustic vibrations. Furthermore, TMV is commonly used as an imaging standard since it has a highly conserved structure.

Parasites

Parasites of size 25 µm x 25µm can be measured in the air using AFM. These Leishmania cells have been treated with an antimicrobial peptide, leading to highly roughened cell membranes, which can be measured and quantified by AFM.

Epithelial Cells

Epitheleal cell of size 32 µm x 32 µm can be measured in liquid using Atomic Force Microscope. Measurement of high-resolution images of cells in a liquid (e.g., under physiological conditions) is another possibility unique to AFM and can give much more relevant results than electron microscopy, which requires cell fixation, leading to artifacts.

Atomic force microscopy has a particular advantage over electron microscopy, in that cells and biomaterials can be imaged in partially or totally hydrated conditions including ambient air and liquid environments.

Recommended AFM products for life sciences applications are TT-2 Atomic Force Microscope and LS-Atomic Force Microscope. To buy high-quality Atomic Force Microscope, feel free to visit https://www.afmworkshop.com/.
