Hydroxymethylation as a Novel Environmental Biosensor [PDF]

open access: yesCurrent Environmental Health Reports, 2014
Beyond the genome, epigenetics has become a promising approach in understanding the interactions between the gene and the environment. Epigenetic regulation includes DNA methylation, histone modifications, and non-coding RNAs. Among these, DNA methylation, which is the addition of a methyl group to the fifth base of cytosine to produce 5-methylcytosine

Direct Surface Modification of the Epidermis Using Mussel‐Inspired Polydopamine with Multiple Anti‐Biofouling Functions

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface modification using mussel‐derived polydopamine (PDA) is a versatile and robust biocompatible strategy that enables direct application to various epidermal surfaces, regardless of their morphological complexity or surface characteristics. The PDA‐coated epidermis exhibits multiple anti‐biofouling functionalities, including antibacterial and anti‐

Supramolecular Conductive Hydrogels With Homogeneous Ionic and Electronic Transport

open access: yesAdvanced Materials, EarlyView.
Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) based conductive hydrogels have received great attention in bioelectronics on account of their tissue‐like mechanical properties. However, inhomogeneous morphologies of the conducting PEDOT phase limits their electrical and mechanical properties. Here, supramolecular hydrogels with self‐
