Nanoprobes with barcodes can sense multiple active proteases in parallel
Dec 12, 2023 (Nanowerk News) Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making it important to have methods that can selectively detect active...
How does corrosion happen? New research examines process on atomic level
Dec 11, 2023 (Nanowerk News) When water vapor meets metal, the resulting corrosion can lead to mechanical problems that harm a machine’s performance. Through a process called passivation, it also can form a thin inert layer that acts as a barrier against further deterioration. Either way, the exact chemical reaction...
