Dr Maria Treresa Giardi, Manager of Research at CNR-Area of Research of Rome, is expert on biosensors, biochips based on proteins, enzymes, cells, nanoscience, manufactured tech, industrial technology, biochemical mechanisms in photosynthesis, electron transfer, nutrition, biochemistry. In particular she is dedicated to biotechnological applications of photosynthetic proteins: biochips, biosensors and biodevices mainly based on the recent photosystem II research and the systems available for the bioassay of pollutants using biosensors that are based on the photochemical activity. She developed data as a basis for the development of commercial biosensors for use in rapid pre-screening analyses of photosystem II pollutants, minimising costly and time-consuming laboratory analyses. She was involved in founding the company Biosensor (www.biosensor.it) dedicated to research and commercialization of biosensors. Coordinator and participant of several EU projects on biosensors for environmental monitoring. Coordinator of ESA-ASI-NASA projects for flying biosensors to Space and to ISS.

Electrochemical biosensors are becoming fairly popular in the world. However, one of the limits of those developed until now is represented by the lack of methods providing stable and highly efficient junctions between biomaterial and solid state devices. The present article shows how laser-induced forward transfer (LIFT) can represent a valid tool to ensure an efficient electron transfer from selected photosynthetic biomaterials such as thylakoids, to screen-printed electrodes used as solid support and transducers for the biomaterials themselves. The ideal pattern, in terms of photocurrent signal of thylakoid droplets, giving a stable response signal with current intensity of about 335 ± 13 nA, with a thylakoid mass of 28 ± 4 ng, was selected. It is shown that the efficiency of energy production of a photosynthetic system can be strongly enhanced by LIFT process, as demonstrated by the application of the technique for the construction of an efficient and sensitive photosynthesis-based biosensor useful for the detection of herbicides in the nanomolar range (LOD(diuron) 8.0 × 10-9?, LOD(linuron) 4.0 × 10-9?).
