“…The discrepancy should be attributed to the difference in their real contact areas. Nanoscale frictional force is believed to be approximately proportional to the real contact area [52][53][54][55]. The Al 2 O 3 NW surface studied here is rougher than the Si substrate studied previously [32].…”

The adhesion and friction between two AlO nanowires (NWs) was characterized by the use of optical microscopy based nanomanipulation, with which peeling, shearing and sliding was performed. The elastically deformed shape of the NWs during peeling and shearing was used to calculate the adhesion and frictional forces; force sensing was not required. The obtained adhesion stress between two AlO NWs varied from 0.14 to 0.25 MPa, lower than that observed for carbon nanotube junctions, and was attributed to van der Waals attraction. Stick-slip was observed during the shearing and sliding of two NWs, and was the consequence of discrete contact between surface asperities. The obtained static and kinetic frictional stresses varied from 0.7 to 1.3 MPa and 0.4 to 0.8 MPa, respectively; significantly greater than the obtained adhesion stress.

“…Consequently, the friction force, directly proportional to the real contact area, decreases on substrates with uneven surface topography. 126,139,196,222 Conversely, 1D materials may conform to the topography of a substrate, resulting in a notable increase in friction compared to its bulk counterpart. This increase is widely accepted as the primary contributor to the elevated friction/adhesion observed in gecko-like ber-based adhesives.…”

“…In particular, this OM-based nanomanipulation method has become one of the primary approaches for systematically characterizing the mechanical behavior and surface mechanical properties of NFs, through the combination with external manipulators, MEMS, or force/ displacement sensors, and other micro-nano devices. 126,139,142,183,[216][217][218][219][220][221][222] 3.3.1.

“…This capability has facilitated the mechanical characterization of NWs using relatively low-cost OM imagingbased read-out strategies. The arc-shape of NWs sliding along a substrate has been used to quantify their static and dynamic friction (Xie et al, 2017;Xie et al, 2018b). The loop diameter of fractured NWs have been used to quantify their fracture strength (Wang et al, 2015;Roy et al, 2017).…”

The micro- and nanoscale characterization and mapping of surface properties and surface behaviour is critical to both physical and biological science. Mechanical contact probes are a critical tool for investigating surface and interface science, and have seen greater development and a diversification in recent years. In particular, mechanical contact probes that have been fabricated from the bottom-up by the assembly of synthesized nano- or microscale materials can provide enhanced functionality and sensitivity over traditional microcantilevers. This work provides an overview of recent developments in the field of assembled micro- and nanoscale mechanical contact probes, with a specific focus on three probe types: colloidal particle probes with high aspect ratio and a high lateral sensitivity, one-dimensional probes comprising of nanotube and/or nanowire deflection elements, and liquid metal-based probes. For each probe type, the state-of-the-art is reviewed, and their assembly, design, functionality and capabilities are discussed. An outlook on the future direction of probe development and potential applications is also given.
