Investigation of Proteinoid Microspheres for Cellular Nanonetworks Based on Frequency Response

There is a growing interest in proteinoid (thermal proteins) microspheres as a potentially valuable components for creating nano-scale sensing and computing networks. This research aims to investigate how proteinoid microspheres respond to different frequencies and assess their potential for use in cellular nano-scale communication networks. An analytical model is developed to establish a connection between input and output signals across a proteinoid microsphere, based on its material properties. This model is then tested through experiments using proteinoid microspheres created through thermal condensation. Our findings reveal that the electrical properties of proteinoid microspheres vary based on their composition, with impedance, resistance, and capacitance values covering a wide range. By utilizing equivalent circuit modeling, we gain a deeper understanding of how their frequency response is linked to their structural characteristics. Some proteinoids exhibit intriguing behaviors, such as negative capacitance, suggesting possibilities for tailoring their dielectric properties through engineering. Adjusting the amino acid composition of these microspheres allows for customization of their frequency response, potentially enhancing signal transmission. The proposed modeling approaches provide valuable insights for optimizing nano-transceivers based on proteinoids. By establishing a correlation between composition and electrical traits, we gain a framework for improving proteinoid-based nano-transceivers. This study provides a comprehensive exploration of how proteinoid microspheres can contribute to the diverse range of frequency responses achievable in advanced nano-bioelectronic systems.
