“…Based on film deposition techniques (e.g., electroless plating, sol-gel process, ultrasonic chemical method), the delicate shapes and structures can be directly replicated, which provides an effective way to fabricate structural monomers with diversity in geometric features and also promising properties. [68][69][70] To date, various microorganism species with typical shapes have been used for biotemplated forming, including Chlorella, [71][72][73][74] yeast, [75][76][77] bacillus, [78][79][80] Escherichia coli., [81][82][83] virus, [84][85][86][87][88] Spirulina, [89][90][91][92] and diatoms. [93][94][95][96][97] Based on microbial extracellular forming technique, a range of functional microparticles with various shapes and coating materials have been fabricated, including microspheres, microrods, microflakes, microcoils, etc.…”
