Facile synthesis for colloid silica cross-linked threadlike micelles based on block copolymer self-assembly

► We propose a route for the synthesis of a new class of colloid silica cross-linked threadlike micelles. ► The threadlike hybrid micelles form from individual micelles by silica deposition. ► The threadlike hybrid micelles is the intermediate in the formation of SBA-15. ► The threadlike hybrid micelles have significantly improved stability against dilution. ► The threadlike hybrid micelles as drug carrier have a higher loading capacity and a slower release rate.
