Summary: Flexible hydrogel sensors have found extensive applications in electronic devices due to their suitable mechanical properties and excellent biocompatibility. However, the current methods for synthesizing reduced graphene oxide (rGO) face limitations in terms of reduction degree and dispersion, which hinder the conductivity of graphene hydrogels. In addition, hydrogels are prone to inflammation and bacterial infections, affecting sensor stability over time. This study successfully synthesized a hydrogel with commendable conductivity and sensor performance by modifying and reducing GO using a heparin-polydopamine complex. The multifunctional nature of this hydrogel makes it a promising candidate not only as an epidermal sensor but also for chronic wound treatment.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.
