Microparticle

A new study using microparticle therapy to boost the number of ‘good’ immune cells has reversed the nerve cell damage in mice with multiple sclerosis-like symptoms and cured more than a third. The finding has the potential to lead to new treatments for not only multiple sclerosis but other autoimmune diseases like type 1 diabetes.Multiple sclerosis (MS) is an incurable autoimmune disease caused by the body’s immune cells mistakenly attacking the nerves that send information to the brain and spinal cord. The condition…

Physicists observed a microparticle curving around a cylindrical obstacle and sticking to its backside, rather than colliding into it or sailing around it. Researchers discovered that electrostatics, hydrodynamics, and erratic random movement of the surrounding molecules caused this unexpected trapping behavior. The size of the obstacle determined how long the particle remained trapped before escaping. These new insights could be used to improve microfluidic applications and drug delivery systems that use microparticles…
