Introduction - Adiantum

Adiantum, also called maidenhair ferns, has been the subject of intense research for their surface characteristics and medicinal properties.

The name ‘Adiantum’ is originated from the Greek word of meaning ‘not wetting.’ This refers to the hydrophobic nature of the surface. Like the lotus leaf, which is extensively studied for its superhydrophobicity, Adiantum repels water using wax crystal microstructures.

Atomic Force Microscopy (AFM)

AFM is a highly useful analytical technique in the phytology field for the analysis of surface characteristics.

The requirement for the deposition of a thin conductive layer and the subsequent placing of the sample in a vacuum as in the case of scanning electron microscopy (SEM) often modifies the physical properties of the biological surface.

However, the AFM imaging of plant surfaces holds potential for species comparisons and taxonomy. Figures 1 and 2 show a 10µm x 10µm AFM phase scan of Adiantum epicuticular wax structures and a 10µm x 10µm AFM 3D image of Adiantum epicuticular wax structures, respectively. In addition, AFMs can be used in industrial applications, for instance to ensure the quality of botanical drugs and foods.

P100 AFM

The P100 AFM from Ardic Instruments has a sub-nanometer Z spatial resolution, which allows for high-resolution imaging and measurement. The combined open-loop and low-noise scanner enables rapid and effective experiments up to 15µm by 15µm. The innovative astigmatic optical design generates a small 0.56µm laser spot size that enables users to experiment with more compact and faster AFM cantilevers.

In addition, the P100 AFM includes PSX control software, which is highly intuitive and enables users to complete experiments with the least amount of training. The setup and scan process is automated by the one-click scan feature, thereby enabling users to acquire high quality scan results quickly. The integrated scan library management feature facilitates the flagging of scan data and enables users to export or delete scans with ease.

Conclusion

The P100 AFM simplifies the setup and scanning process, thereby enabling the field of phytology to acquire in-depth 3D images quickly, with least amount of training.
