Controlled Deformation of Soft Nanogel Particles Generates Artificial Biominerals with Ordered Internal Structure
© 2023 Wiley-VCH GmbH..
Biominerals can exhibit exceptional mechanical properties owing to their hierarchically-ordered organic/inorganic nanocomposite structure. However, synthetic routes to oriented artificial biominerals of comparable complexity remain a formidable technical challenge. Herein we design a series of soft, deformable nanogels that are employed as particulate additives to prepare nanogelcalcite nanocomposite crystals. Remarkably, such nanogels undergo a significant morphological change-from spherical to pseudo-hemispherical-depending on their degree of cross-linking. This deformation occurs normal to the growth direction of the (104) face of the calcite and the underlying occlusion mechanism is revealed by in situ atomic force microscopy studies. This model system provides new mechanistic insights regarding the formation of oriented structures during biomineralization and offers new avenues for the design of synthetic nanocomposites comprising aligned anisotropic nanoparticles.
