Welcome to the page devoted to the BIOSensor Systems of the laboratory affiliated with the University of Florence, known as GEABio. Here our team of researchers guided by Professor Elisabetta Meacci, along with contributions by experts such as Dr Giancarlo Margheri, Professor Edgardo Giordani, and Dr Antony Chirco of the ‘Mario Serio’ Department of Biochemical, Experimental, and Clinical Sciences at the University of Florence, are committed to advancing technology for sustainable monitoring and biomolecular research.

Goal of the project

The project proposes to develop and apply high-resolution operating systems for monitoring the well-being of plants and of biodiversity. Through the study and characterisation of bioactive molecules with healthy properties in plant systems, we hope to contribute to environmental and agricultural sustainability.

Operating principle: SPR (Surface Plasmon Resonance)

The resonant absorption of films of noble metals occurs in correspondence with a specific angle of incidence, dependent on the mass of the material deposited on the external interface of the metal. We use this advanced technology for precise analysis of biomolecules and their effect on the plant environment.

Research activities

  • Development of specific sensors for detecting biomolecules
  • Identification and quantification of biomolecules, markers of toxicity/pathogens, and biomolecules with healthy properties
  • Functionality of transducers for high-resolution acquisition of data
  • Training of new professionals in the field of biotechnology

Milestones and future developments

Our prototype for an SPR sensor is already performing very well in the market, but we intend to improve its functionality and the acquisition of data to make it even more effective and accessible. We are involved in research on biomolecules in the cultivation of Moringa oleifera (a fast-growing, drought-resistant tree from India) and on the optimisation of our sensors for better precision and reliability.

Join us in advancing biomolecular research for a more sustainable, informed future.
