Scheme showing the industrial synthetic pathways of engineered SiO2 NPs. The reaction equations 1-12 are given in Supplementary Table 8. The key reactions that may cause significant isotope fractionation of Si or O are marked with asterisks. The dashed line represent a potential but not commonly used route
