Al and Si atomic percentages in frustules and entire diatoms. a The data of Al and Si atomic percentages for BSi-C; b the data for BSi-N; c the data for the entire Cyclotella meneghiniana diatoms; and d the data for the entire Nitzschia palea diatoms. Energy-dispersive X-ray spectroscopy (EDS) spot analysis was used for the determination, and the data of more than 100 spots (specified in the brackets of a‒d) from over 35 entire diatoms or their BSi were collected. R2 is the correlation coefficient between the atomic percentages of Al and Si (the linear fitting formulas are given in Supplementary Table 1). Source data are provided as a Source Data file
