Summary of "Polymer Patterning with Self-Heating Atomic Force Microscope Probes."

Scanning probe-assisted patterning methods already demonstrated a high degree of capabilities on submicrometer scales. However, the throughput is still far from its potential due to complexity or fragility of the probes for exploiting thermal effects, chemical reactions and voltage-induced processes in various patterning operations. Here, we present a new approach to thermomechanical patterning by implementing a multitasking atomic force microscope (AFM) probe: the functionalized planar probes (FPPs). In this method, we can generate a tunable thermal gradient between the tip and the sample wherein they remain in non-contact regime. In principle, the capillary instability provoked by the van der Waals interaction yields a pull-off force towards the tip. Hence, locally rising protrusions form features at any selected position on a polymer surface without any chemical reaction or irreversible transformation. These multitasking probe integrated AFMs can pave the way for a remarkable freedom in determining the operation regime on submicrometer surface patterning applications.

Medical and Biotech [MESH] Definitions

The processes occurring in early development that direct morphogenesis. They specify the body plan ensuring that cells will proceed to differentiate, grow, and diversify in size and shape at the correct relative positions. Included are axial patterning, segmentation, compartment specification, limb position, organ boundary patterning, blood vessel patterning, etc.

Scanning microscopy in which a very sharp probe is employed in close proximity to a surface, exploiting a particular surface-related property. When this property is local topography, the method is atomic force microscopy (MICROSCOPY, ATOMIC FORCE), and when it is local conductivity, the method is scanning tunneling microscopy (MICROSCOPY, SCANNING TUNNELING).
