Fiber-assisted nanoparticle tracking analysis meets nanorheology: a novel approach for probing viscoelastic properties at the nanoscale.

ABSTRACT: This study introduces fiber-assisted nanoparticle tracking analysis (FaNTA) as a platform for nanorheology that utilizes an advanced antiresonant optical fiber to analyze the viscoelastic properties of fluids at the nanoscale. The platform confines colloidal nanotracers within a fiber-integrated microchannel, significantly extending observation times and improving statistical accuracy. The FaNTA system consists of a custom-designed microstructured antiresonant fiber, a dedicated optical setup, and sophisticated data processing including image analysis and statistical filtering, enabling precise determination of the hydrodynamic diameter and thus the local viscosity. The study demonstrates the capabilities of the FaNTA concept in the context of rheology by measuring the viscosity of glycero
