Applied Nano, Volume 6, Issue 1

March 2025 - 5 articles

Cover Story: DNA-encoding bacterial 16S rRNA acts as nano-sized storage revealing soil bacterial communities. This ‘nano-archive' not only characterizes recent local ecology but also unveils human impacts on soils over time, crucial for archaeology and understanding past human activities' ecological effects. Advanced sequencing methods like Illumina enable parallel determination of diverse DNA sequences, efficiently reflecting soil bacterial community compositions in topsoil layers and at archaeological sites like settlements, burials, and workplaces. This overview highlights recent molecular developments in studying archaeological soil samples with typical examples. View this paper
