Three-dimensional (3-d) gold microstructures with complex architecture were prepared from silica-based diatom microshells (frustules) using template synthetic process based on the electroless metal (gold) deposition. Diatom frustules were replicated into gold microstructures with a high-precision, entirely preserving their shape and micro and nanoscale porous features.
A two-step electrochemical anodisation approach was adopted in this work to create a series of highly ordered mesopores etched with different diameter (60 to 160 nm) and uniform nanotube length in anodised aluminium oxide (AAO). The loading and release characteristics of model drug (indomethacin) and drug carriers (micelles named Pluronic F127, TPGS, PEO-PPO-PEO) were presented to investigate the...
