Fig. 3From: Enhancement of hemostatic properties of Cyclotella cryptica frustule through genetic manipulationCharacterization of diatom frustules. EDXS analysis of WT, A-5, A-4, and A-2 are shown in a–d; element content, FTIR spectra, and zeta potential of four C. cryptica lines are shown in e–g. A-2, A-4, and A-5 represent the antisense RNA clones; * indicates the significant difference from WT (p < 0.05)Back to article page
