Abstract: We present results for algae (R. subcapitata) delayed luminescence when exposed to stressing compounds, showing good sensitivity as fast as 1h after inoculation. The utilization of the photonic approach, which involves reduced sample sizes and shorter preparation and cultivation has the potential to yield earlier outcomes when compared to conventional methods Ver menos
