Injectable water filtration system could improve access to clean drinking water around the world

Short article about promising water filtering that is also cost effective.

"Today's options for portable water filtration of tiny particles mostly consist of filter paper and microporous membranes. According to the research, these devices filter out roughly 40% and 80% of particles larger than 10 nanometers, respectively. This new system catches close to 100% of these particles.

And it is made of low-cost, sustainable, readily available materials. The main innovation is an intertwined web of nanocellulose fibers that catches particles while the newly cleaned water passes through."
