ZnO Superstructures as an Antifungal for Effective Control of Malassezia furfur, Dermatologically Prevalent Yeast: Prepared by Aloe Vera Assisted Combustion Method

In this paper, a robust and simple biogenic route has been developed to synthesize self-assembled ZnO superstructures in short intervals of time using naturally available aloe vera plant gel and zinc nitrate as starting materials. The stabilization of zinc ions with polysaccharides wrapped chains along with the support of proteins, lipids and physterols of aloe vera gel followed by combustion derives the ZnO superstructures. The obtained ZnO superstructures show a hexagonal crystal phase and exhibit a semiconducting behavior with the energy band gap varies from 2.92 to 3.08 eV. The aloe vera gel derived ZnO superstructures exhibit unique and strong orange-red emission centered at 600 nm. The better structural, morphological and photoluminescence results are obtained for ZnO prepared with 16.6% W/V of zinc nitrate with aloe vera content compared to other concentrations of aloe vera. The prepared compounds are tested for antimalassezial activity against Malassezia furfur, dermatologically prevalent yeast, a...
