Summary
This laboratory study presents a novel microfluidic platform integrating electrokinetic microdevices with 3D microelectrodes to enable real-time, label-free assessment of membrane integrity in live neuronal cells. The platform measures changes in plasma membrane capacitance in response to different aggregated forms of α-Synuclein, a protein implicated in Parkinson's disease pathogenesis, providing whole-membrane sensitivity and single-cell resolution. The technology enables time-resolved comparison of membrane-disruptive effects across monomeric, oligomeric, and fibrillar protein conformations, potentially offering improved methods for studying neurodegenerative disease mechanisms.
UK applicability
This foundational laboratory methodology is not directly applicable to UK farming or food systems but may inform UK-based neuroscience research on neurodegenerative disease mechanisms and could support development of biomarker or diagnostic tools relevant to clinical and research settings.
Key measures
Plasma membrane capacitance changes measured via electrorotation responses; single-cell level analysis; throughput of up to 30 live neuronal cells per hour; membrane integrity assessment across different α-Synuclein conformational states
Outcomes reported
The study developed and validated a microfluidic platform capable of real-time, label-free measurement of plasma membrane integrity in live neuronal cells by analysing dielectric properties via electrorotation. The platform quantified differential membrane-disruptive effects of monomeric, oligomeric, and fibrillar α-Synuclein conformations at single-cell resolution across the entire membrane surface.
