There is a continuous vivid search for biocompatible hybrid magneto-optical nanoprobes with high heating and photoluminescence efficiencies photothermal theranostics. Herein, two tailored multipurpose PEGylated gold (Au) silver sulfide (Ag2S) magnetic iron oxide nanoparticle formulations (Au-PEG-MNPs Ag2S-PEG-MNPs) unique opto-magnetic properties simultaneous therapy were prepared. The physiochemical of the MNPs fully characterized using various electronic spectroscopic techniques, showing colloidal stabilized small-sized nanoparticles (core sizes = 10 nm, DH 200 nm) saturation magnetizations (Ms up to 85 emu/g) superparamagnetic behavior. Thermal effects in response an alternating field (AMF) at different frequencies (f 25–300 kHz) intensities (H 12 24 kA/m) assessed ultrafast magnetometric method, revealing distinctive responses. "optothermal" efficacies then evaluated experimental setup equipped highly sensitive thermal camera recording temperatures real time, along clinically safe near-infrared (NIR) laser (λ 808 nm power 0.5 W cm–2) AMF kA/m, f 180 dual effect. Remarkably, when irradiated NIR AMF, both Au- Ag2S-PEG-MNPs displayed superior heat induction (SAR 384 441 W/g), rapidly reaching hyperthermia 42 °C only few seconds. Temperatures could reach 75 Au-PEG-MNPs 90 5 min. Such increased ∼1.5–2 times under concurrent irradiation compared action by alone. Finally, cytotoxicity assays against cancerous normal cells confirmed safety profiles low toxicities nanoformulations. This synergistic platform has great potential be utilized multimodal reduced strengths, intensities, short unceasing tangible hyperthermal clinical nanoprobes.
