When white carbon black meets biomedical research, a cross-border revolution is happening. In the field of tissue engineering, 3D printed white carbon black/sodium alginate composite scaffolds exhibit excellent bone conductivity, and their porous structure can guide the directional growth of bone cells, reducing fracture healing time by 40%. In terms of drug delivery, mesoporous silica nanoparticles achieve precise release of anticancer drugs at the tumor site through a pH responsive gating system, reducing toxicity by 60% and increasing efficacy by three times. Even more exciting is that scientists have discovered that specific morphologies of white carbon black can regulate the behavior of immune cells, providing new strategies for the treatment of autoimmune diseases. These studies reveal that white carbon black is not only an industrial material, but also a potential stock for future precision medicine.
