Arthrospira platensis, called spirulina (Sp), is known to bind a wide range of heavy metals. We propose an innovative approach, based on Spirulina as bioreceptor combined with highly sensitive Love wave platform for fast detection of heavy metals in solution. Our goal is to optimize the biofunctionalization of the sensor surface with microalgae, based on real-time responses of the acoustic sensor during Spirulina immobilization then heavy metals detection, combined with atomic force microscopy characterization to...
