1 Next, the cis-diol group of ribose sugar at the end of the miRNAs chain allowed 3-aminophenylboronic acid (APBA)/biotin-modified multifunctional AuNPs (denoted as APBA-biotin-AuNPs) to be attached through the formation of a boronate ester covalent bond, which facilitated the capture of streptavidin-conjugated alkaline phosphatase (SA-ALP) via the biotin-streptavidin interaction. 3-aminobenzeneboronic acid alkaline phosphatase, placental Homo sapiens
