Abstract: ABSTRACT MICROBIALLY DERIVED CELLULSOE ARCHITECTURE-STABILIZED, SURFACTANT-FREE MAGNETIC NANOPARTICLE PLATFORM The present disclosure relates to a surfactant-free magnetic nanofluid platform comprising an aqueous carrier, a microbially-derived cellulose architecture, and magnetic nanoparticles formed and immobilized in association with the microbially derived cellulose architecture. The microbially-derived cellulose architecture is derived from bacterial cellulose and is selected from cellulose nanocrystals, cellulose nanofibrils and intermediate morphologies. The magnetic nanoparticles act as pinning and bridging centres between adjacent cellulose domains to convert an anisotropy-dominant dispersion into regulated segmental networks. The platform enables anisotropy- to-network transduction, morphology-gated fluidization, regime-mapped shear behavior including stable intermediate-shear viscosity, mode-selectable magnetorheology wherein applied magnetic flux density modulates viscosity differently for different formulations, field-threshold and rate-coded magnetic transport, composition-dependent magnetothermal heating under constant alternating magnetic field conditions, and multi-stressor stability retention.
