To solve this, we present a one-pot coating method inspired by marine organisms' adhesive mechanisms, utilizing the exceptional properties of polydopamine. Known for its hydrophilicity and versatile affinity for various substrates, polydopamine acts as a robust adhesive polymer, enhancing the attachment of neutravidin to sensor surfaces. This improves antibody immobilization through strong avidin-biotin interactions, leading to a significant increase in detection sensitivity. Validation with model biomarkers showed more than a tenfold improvement in sensitivity compared to commercial immuno-plates. This approach highlights the transformative potential of polydopamine in biosensor technology, offering a straightforward and effective solution to enhance biosensor performance in diverse biological applications. 2024-09-29T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/47026 Title: Injectable hydrogel system with controlled adhesion on soft tissue Author(s): Hong, Seonki 2017-11-23T15:00:00Z
