Figure 4: TMOS/MPTMS T. weissflogii retains nano-scale architectural features.
From: Functionalization of the living diatom Thalassiosira weissflogii with thiol moieties
SEM micrographs of (a) T. weissflogii and (d) TMOS/MPTMS T. weissflogii. Scale bar, 10 μm. Surface topography of the valve surface of (b) T. weissflogii and (e) TMOS/MPTMS T. weissflogii imaged using AFM illustrating the characteristic features in the centre of the valve. TEM micrographs of (c) T. weissflogii and (f) TMOS/MPTMS T. weissflogii illustrating the decreased pore parameters in the modified diatom. Scale bar, 500 nm (g) Distance between ribs is decreased in TMOS/MPTMS T. weissflogii. Data are shown as mean±s.e.m. (Rotational distance n⩾75 measurements, Radial distance n⩾35 measurements) t-test revealed significant difference between groups *P<0.05, ***P<0.001. (h) Architectural properties of the pores on the valve surface are reduced in TMOS/MPTMS T. weissflogii. Data represent mean±s.e.m. (n=3) t-test revealed significant difference between groups **P<0.005, ***P<0.001 (i) The density of pores on the valve surface is unaltered. Data represent mean±s.e.m. (n=3).
