Panagiotis Mougkogiannis, Andrew Adamatzky
TL;DR
This study explores how paclitaxel interacts with proteinoid microspheres to create electrically active networks with potential applications in bio-inspired signal processing.
Contribution
The study introduces a novel paclitaxel-proteinoid system that exhibits enhanced conductivity and oscillatory behavior.
Findings
Paclitaxel incorporation into proteinoid microspheres increases electrical conductivity by nearly two orders of magnitude.
The system shows diffusion-controlled redox behavior and long-term stable electrical oscillations.
Spectral analysis reveals chaotic behavior in mixed proteinoid systems.
Abstract
Paclitaxel is a widely used microtubule-targeting chemotherapeutic, yet its intrinsic electrochemical behavior remains poorly understood. Here we investigate the electrochemical and oscillatory properties of paclitaxel incorporated into proteinoid microspheres that mimic cellular environments. Using scanning electron microscopy, cyclic voltammetry, electrochemical impedance spectroscopy, and square-wave voltammetry, we compare pure paclitaxel, proteinoid–paclitaxel mixtures, and related proteinoid systems. Incorporation of paclitaxel induces the formation of interconnected fibrous networks and enhances electrical conductivity by nearly two orders of magnitude relative to pure paclitaxel. The proteinoid–paclitaxel system exhibits diffusion-controlled redox behavior, long-term stable electrical oscillations, and high signal coherence. Spectral and nonlinear analyses reveal distinct…
