Enhancing the substrate selectivity of enzyme mimetics in biosensing and bioassay: Novel approaches

for modification. Despite these advantages, the main challenge for artificial enzyme mimetics is the lack of substrate selectivity where natural enzymes flourish. This review addresses of artificial enzymes
