Hybrid and composite systems that mix two distinct material classes — polymer-metal-oxide nanocomposites, carbon-polymer composites, and core-shell or milled-oxide hybrids.
A gold nanoparticle's surface charge, more than its size, governs whether it aggregates inside a hydrogel: negatively charged particles aggregate while positively charged ones stay dispersed.
A PANI-CdO nanocomposite with 10 wt% CdO outperforms the authors' earlier PANI-only sensor, reaching a room-temperature methanol response of 1580 with fast recovery.
A PANI-ZnO nanocomposite thin film with 20 wt% ZnO gives the strongest, most selective room-temperature methanol response among several tested loadings, responding in just 7 seconds.
A bio-derived Pebax polymer loaded with just 0.4 wt% carbon nanotubes becomes a sustainable, multi-stage piezoresistive strain sensor that stays stable over 1,000 stretch-release cycles.
A TiO2-Mn3O4 hybrid electrode detects glucose without any enzyme, reaching a 0.01 micromolar detection limit and successfully measuring glucose directly in fruit samples.
A V2O5-graphene oxide hybrid made by electrochemical exfoliation offers a lower-cost, non-noble-metal alternative for direct glucose electrooxidation and sensing.
Zn-loaded PLLA nanosheets release therapeutic zinc ions steadily over 10-12 hours and show antibacterial activity against E. coli, supporting their use as wound-healing patches.
A one-pot, chemical-free laser-ablation route sequentially builds ZnO@graphene-oxide core-shell nanoparticles in water, with longer graphite ablation producing thicker GO shells.
An Au/ZnO-PVA/CAT/Chitosan biosensor detects hydrogen peroxide with a 9.13 nanomolar detection limit and under 1-second response time, validated directly in human blood serum.
