Abstract
The utilization of natural compounds, such as phenolic acids and biopolymers, in the healthcare domain is gaining increasing attention. In this study, bacterial nanocellulose (BC) membranes were loaded with ionic liquids (ILs) based on phenolic acids. These ionic compounds, with improved solubility and bioavailability, were prepared by combining the cholinium cation with anions derived from caffeic, ellagic and gallic acids. The obtained BC-ILs membranes were homogeneous, conformable and their swelling ability agreed with the solubility of each IL. These membranes revealed a controlled ILs dissolution rate in the wet state and high antioxidant activity. In vitro assays performed with Raw 264.7 macrophages and HaCaT keratinocytes revealed that these novel BC-ILs membranes are non-cytotoxic and present relevant anti-inflammatory properties. Diffusion studies with Hanson vertical diffusion cells showed a prolonged release profile of the ILs from the BC membranes. Thus, this work, successfully demonstrates the potential of BC-ILs membranes for skin treatment.

Abstract
Because of the advantages of nanoparticles (NPs) in a variety of industrial, biomedical, and consumer applications, they are intentionally (such as in medicine) or unintentionally (environment exposure) introduced into the human body. However, to date, the detrimental effects of NPs are still unclear, especially in reproductive and developmental toxicity. In this study, we researched 266 articles related to the reproductive and developmental toxicity of NPs from 2006 to December 2016 based on the database of the Web of Science. According to the bibliometric analysis, we found that China and the United States were the leading countries in this field and the major research trends might focus on the pathogenesis of NPs, such as oxidative stress, inflammation, and DNA damage. By this analysis, we provide new insights into the research trends and characteristics of the field.
