N2 - In this paper, we propose a biosensor chip composed of metamaterials and a cavity for label-free measurements of in vivo-like cells. The ~50 μm thick cavity effectively reduces water absorption of terahertz waves, maintains an aqueous environment, and ensures consistent sample thickness. The biosensor chip effectively distinguishes between different densities of Neurons, demonstrating a resonance frequency difference of ~50 GHz. This study introduces a highly sensitive terahertz detection method for cells in an in vivo-like condition, offering a new, rapid, cost-effective, and highly sensitive approach to biosensing.
