(A) Schematic illustration of the strategy to modify MBs with ssDNA-invertase and generate MB-ssDNA-invertase. (B) FTIR analysis to demonstrate successful modification of ssDNA-invertase on streptavidin MBs. The dashed lines indicate the infrared absorption of phosphate backbone (1,090 cm−1, red), deoxyribose C-O (1,050 cm−1, red), deoxyribose rings (890 cm−1, red) and amide bands (1,620 cm−1, and 1,540 cm−1, brown).
