Despite the limited performance, the project remains a proof of concept that pig skin can absorb medication delivered through a dissolvable microneedle patch. The research team also found that the patches work better on the neck than the ear. No adverse responses were observed at application sites, highlighting the safety and tolerability of the patches. Additionally, a new approach is being developed using the microneedle patch technology as a way to incorporate tattoos for animal tagging.
Snow and ice can damage paved surfaces, leading to frost heaves and potholes. These become potential hazards for drivers and pedestrians and are expensive to fix. Now, researchers propose in ACS Sustainable Chemistry & Engineering a figurative and literal green solution to improve the durability of roads and sidewalks: an algae-derived asphalt binder. For temperatures below freezing, results indicated that the algae binder reduced asphalt cracks when compared to a conventional, petroleum-based binder.
