WebApr 10, 2024 · In terms of medicine, the prevention, diagnosis, and assessment of acute myocardial infarction (AMI) as well as the effectiveness of therapy all depend on the sensitive and early detection of human heart-type fatty acid–binding protein (H-HABP). The synthetic material used in this study, Ni-TCPP(Fe), has a unique structure that resembles … WebIn this case, the micromotors are usually made from or composed of Pt or Au, which can act as catalase. With the catalysis, H 2 O 2 can be decomposed into O 2 and H 2 O. The excessive generation of O 2 bubbles can create the recoil force for propelling the micromotors. It is worth mentioning that the velocity of micromotors is influenced by the ...
