Scientists have created a novel method to distinguish between healthy and senescent cells using electric fields, marking a fresh start in ageing research. The frequency-modulated dielectrophoresis (FM-DEP) technique is label-free, rapid, and easy to apply, allowing for the characterization of cell type by measuring the cutoff frequency.
A new device using dielectrophoresis selectively isolates Mycobacterium tuberculosis from sputum samples, providing a purified sample for molecular confirmation. The technology has shown promising results in detecting TB in underserved areas, with high concordance rates compared to culture diagnosis.
A Japanese research team developed a new microfluidic chip that uses dielectrophoresis to sort living cells in just 30 minutes. This technology eliminates the need for labor-intensive sample pretreatment and chemical tagging techniques, preserving cell structure and enabling faster separation of differently sized cells.
Researchers at North Carolina State University have developed a method for creating electrical circuits using self-assembling colloidal nanoparticles under the influence of an alternating current electric field. The process, known as dielectrophoresis, allows microwires to form spontaneously and can be used in wet environments.
