WITHDRAWN: The multi-integrated DNA Bioinspired hydrogel with synergic effect of MB and AuNP with conductive, self-healing, and antibacterial properties as a wearable skin-like sensor

Abstract

In recent years, the world of wearable technology has witnessed groundbreaking advancement with the development of hydrogels in transdermal skin wearable patches. However, it remains a huge challenge to develop hydrogel-based wearable skin-like sensors with superconductivity, high sensitivity, and self-healing properties. On the other hand, the use of biomaterials such as borax hydrogel in wearable technology enables the development of flexible but not with excellent electrical conductivity and tensile strain. Here, we introduce a novel DNA bioinspired by PVA-AuNP-DNA-MB-MXene (PADMM)-borax hydrogel, which could bring both improve properties of the highly strain sensitive (GF = 4.9), self-healing (within 10 min, 93% healing efficiency), and excellent antibacterial activity. Here, the ion conductivity and antimicrobial effects could be improved by the synergistic effect of AuNPs and the MB effect in the multi-integrated DNA bioinspired network compared to the PVA-MB-DNA-MB-MXene-borax hydrogel (PDMM)-borax and PVA-MXene (PM)-borax hydrogels. Our hydrogel showed perfect ability as a wearable skin-like sensor to monitor human movement, including large deformations (finger, elbow, wrist) and tiny deformations (mouth movement) in real-time. Thus, our DNA-bioinspired PADMM-borax hydrogel combines therapy appeal with strong functionality as a transparent patch, opening up a world of possibilities in various industries for personalized healthcare monitoring.
