Because of the small applied forces (< 50 nN), the shape of the droplet can be described by the Young-Laplace equation, which is not the case for highly-deformed EGaIn coneshaped tips. In our experiments, the oxide layer also remains intact even after multiple force spectroscopy measurements. For a spherical droplet of radius R = 5 µm with a contact radius r = 1 µm (corresponding to the maximum loading conditions of Fig. ), we estimate the strain experienced by the oxide layer to be & ≈ 1/32 (r/R) 4 ≈ 2×10 -3 or 0.2 %, below the reported yield strain of about 1% 50 (See derivation in Supporting Figure ). The presence of an intact oxide is reflected in the absence of roughness/wrinkles in the SEM image and AFM topography map of the droplet in Figure and Supporting Figure , both taken after performing several force spectroscopy measurements on the EGaIn droplet indicating the robustness of the droplet probe tips. In contrast, the oxide layer can rupture when applying much larger loading forces (in the order of 100 µN), resulting in concentric cracks on the droplet (See Supporting Figure ). The presence of an intact oxide layer in our EGaIn microdroplets allows us to form stable molecular junctions, which we will describe in the next section.
