White carbon black: an "intelligent drug carrier" for biomedical applications

White carbon black has become an ideal drug carrier material due to its high surface area and good biocompatibility. Through surface functionalization, targeted delivery and stimulus responsive release of drugs can be achieved. For example, grafting pH sensitive polymers onto the surface of white carbon black can rapidly release anticancer drugs in tumor tissues (pH ≈ 6.5) and slowly release them in normal tissues (pH ≈ 7.4), significantly reducing toxic side effects.


In the field of bone repair, the 3D printed scaffold prepared by the composite of white carbon black and graphene has a bone integration speed that is twice as fast as traditional titanium alloys. This scaffold simulates the nanoscale pore structure of natural bone (pore size 50-200 μ m), which can promote osteoblast adhesion and angiogenesis, providing a new solution for personalized medicine. In addition, white carbon black based photocatalysts (such as TiO ₂/SiO ₂ composite materials) can increase the degradation rate of total petroleum hydrocarbons (TPH) in petroleum contaminated soil from 30% to 85% within 60 days by generating hydroxyl radicals, and can be reused more than 5 times, reducing remediation costs by 60%.
