抄録

The analysis of capillary waves in confined microspace by quasi-elastic laser scattering (QELS) method enables surface tension measurements. In contrast to previous works, a simple single-beam-focusing method based on spontaneous capillary wave resonance with its confined size is proposed. The capillary wave resonance has been successfully demonstrated in confined two-dimensional micro surface at circular apertures. Moreover, the surface tension dependence on surfactant concentration has been successfully measured at 44-μm-sized circular liquid surface. This method is expected to be a powerful tool for bio and chemical sensing at micro-/nano-scale liquid interfaces.
