Since they are so non-selective, they can kill or control beneficial microbes as well as both targeted and non-targeted ...

Scientists have shown that a notorious hospital fungus has learned to survive on human skin by feeding on carbon dioxide released at the surface. That metabolic edge helps it persist where infections ...

In biocementation, the overall degree of cementation achieved is constrained by the successful completion of four individual, potentially rate-limiting steps: (i) adsorption of the biocatalyst urease ...

Smart nanogels powered by enzymes move through dense tissue by adapting to local conditions, offering a safer and more effective alternative for targeted delivery in complex environments. (Nanowerk ...

A team of researchers has developed a new biosensor that turns the invisible signals into visible color changes to detect urea levels in a simple way. The sensor works by combining gold nanoparticles ...

The construction industry overuses natural resources and energy, causing numerous environmental impacts (ENSHASSI; KOCHENDOERFER; RIZQ, 2014; MORA-BARRANTES et al., 2018; AKINTAYO et al., 2020). The ...

For more than a century, concrete has been the foundation of our modern civilization’s infrastructure with a stoic permanence. But that strength comes at a cost. Concrete, and the cement that binds it ...

Abstract: This paper presents a fully biodegradable wireless sensor for measurements of soil urea over a large area. The sensor consists of an alginate hydrogel with immobilized urease enzyme and a ...
