Bacterial (BKH1) assisted silica nanoparticles from silica rich substrates: A facile and green approach for biotechnological applications

- A facile green route of SiO2-NPs preparation was proposed, where BKH1 bacterium acts as templates.
- Silica leaching behaviour of BKH1 promises a large scale SiO2-NPs preparation from the silica rich source from harsh environment.
- The fluorescence behaviours of SiO2-NPs signify its potential utility in photonics, particularly in biomedical area.
