Dually functionalized dendrimer for stimuli-responsive release of active ingredients into the skin.

The skin, our largest organ, protects against environmental dangers but is vulnerable to various conditions like infections, eczema, dermatitis, psoriasis, skin cancer, and age-related collagen and elastin degradation. Its outer layer, the water-impermeable epidermis, presents challenges for passive drug delivery to the lower living layers of the skin. An ideal dermal delivery system should penetrate the epidermis and release treatments over time.

Mn and Zn-Doped Multivariate Metal-Organic Framework as a Metalloimmunological Adjuvant to Promote Protection Against Tuberculosis Infection.

A first-in-class vaccine adjuvant delivery system, Mn-ZIF, is developed by incorporating manganese (Mn) into the zinc-containing zeolitic-imidazolate framework-8 (ZIF-8). The mixed metal approach, which allowed for tunable Mn doping, is made possible by including a mild reducing agent in the reaction mixture. This approach allows up to 50% Mn, with the remaining 50% Zn within the ZIF.
