Magnetic Field‐Modulated Boolean Logic in Proteinoid‐ Fe ₃ O ₄ Hybrid Materials

ABSTRACT Proteinoid‐ nanoparticle composites are a new hope in unconventional computing. They use self‐assembling protein‐like polymers along with the magnetic and electronic traits of iron oxide nanoparticles. This study looks at how Glu‐Phe‐Asp proteinoid microspheres work with nanoparticles. It shows their potential for use in neuromorphic computing. We found spontaneous electrical oscillations in these composites. We also looked at how external magnetic fields (65, 84, and 103 mT) change their oscillatory behavior. Our findings reveal that these composites can emulate Boolean logic gates, with distinct responses to varying magnetic field strengths. nanoparticles boost the proton‐driven spiking in proteinoid microspheres. This leads to adjustable electrochemical behavior. This work shows that proteinoid‐ nanoparticle composites can be a great platform. They can help create bio‐inspired computing systems. These systems may have adaptive functions, save energy, and resist faults. This opens new doors for neuromorphic systems that imitate biological neural networks.
