Santos is currently a junior researcher at LEPABE, FEUP, in the group led by Professor Nuno Azevedo, and the project manager of the European project “DelNAM”. Rita has also collaborated with Biomode.

Talk summary

Bacterial resistance to antibiotics is one of the most pressing global health problems of our time. Antibiotics resistance calls for alternative drugs and comprehensive diagnostic tools to prolong the lifetime of still valid antibiotics. Oligonucleotides designed to hybridize to selected RNA sequences in bacteria can be used as antisense antibacterial drugs and in vivo diagnostic probes. However, as the bacterial envelope is impermeable to oligonucleotides, they must be delivered by suitable vectors. Several delivery vectors have been studied, including liposomes, peptides, dendrimers and vitamin B12.

Nuno Ratola

Principal Researcher at LEPABE/ENV

Nuno Ratola has a PhD in Chemical and Biological Engineering by FEUP. He has a significant experience in advanced analytical chemistry (sampling, trace analysis, high resolution chromatography) and environmental chemistry, namely in the monitoring and behaviour of legacy and emerging pollutants like siloxanes in several environmental matrices. Currently, he is a Principal Researcher at LEPABE, in the Environmental Sciences and Technologies Research Group, and is leading the project LANSILOT - LAunching New SILOxane Treatments: assessing effluent, sludge and air quality and improving biogas production in WWTPs.

Talk summary

Siloxanes are a growing concern for our environment and have a particularly important presence and effect in WWTPs. The domestic and industrial effluents carry a significant load of these widely used chemicals into these facilities, promoting an extended partition between the water line, the sludge line, and the surrounding air, predominantly the latter two. While the release into the atmosphere may affect firstly the workers of the WWTPs and then the neighbouring, the presence in the sludge can affect not only the quality of the composting products used as a soil additive in several crops but especially the efficiency of the biogas production units, essential for the economic and energetic sustainability of WWTPs.
