Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and physical stress. In addition, the capsule makes the pathogens invisible to our body's own defenses, so to speak, and helps them to survive in the body. /news/2024-07-bacteria-cloaks-invisibility-immune-defenses.html Biochemistry Analytical Chemistry Tue, 30 Jul 2024 09:58:49 EDT news641552320 Realization of an ideal omnidirectional invisibility cloak in free space A team led by Prof. Dexin Ye and Prof. Hongsheng Chen from Zhejiang University, and Prof. Yu Luo from Nanyang Technological University conducted research on the practical implementation of full-parameter transformation optical devices.
