The "Molecular Carrier" of White Carbon Black in the Pharmaceutical Field
Drug release system:
Controlled release capsules: White carbon black/sodium alginate composite microspheres extend the release cycle of ibuprofen from 4 hours to 24 hours, reducing blood drug concentration fluctuations by 60%.
Targeted drug delivery: silica nanoparticles modified with folic acid can absorb 8 times more MCF-7 from breast cancer cells than ordinary preparations.
Biomedical materials:
Bone repair scaffold: 3D printed white carbon black/polylactic acid composite scaffold, with a compressive strength of 40MPa, close to human cortical bone (100-150MPa), and a porosity of 85% to promote osteoblast proliferation.
Wound dressing: silver ion loaded white carbon black water gel has an antibacterial rate of 99.9% against Staphylococcus aureus, and the 7-day healing rate is 40% higher than that of traditional dressing.
Diagnostic application:
Fluorescent probe: After surface modification of Rhodamine B with white carbon black, the detection limit of H ₂ O ₂ reaches 0.1 μ M, which can be used for early diagnosis of cancer.
