Antibacterial and anti-inflammatory effects of Syzygium jambos L. (Alston) and isolated compounds on acne vulgaris
(BioMed Central, 2013)Acne vulgaris is a chronic skin disorder leading to inflammation as a result of the production of reactive oxygen species due to the active involvement of Propionibacterium acnes (P. acnes) in the infection site of the ... -
Antibacterial and photodegradation of organic dyes using lamiaceae-mediated zno nanoparticles: A review
(MDPI, 2022)The green synthesis of zinc oxide nanoparticles (ZnO NPs) using plant extracts has been receiving tremendous attention as an alternative to conventional physical and chemical methods. The Lamiaceae plant family is one ... -
Anticancer and drug-sensitizing activities of gold nanoparticles synthesized from cyclopia genistoides (honeybush) extracts
(MDPI, 2023)Synthesis of gold nanoparticles (AuNPs) using phytochemicals has become tremendously prominent in biomedical applications because of its enhanced bioactivity and biocompatibility. In this study, water extracts from the ... -
Anticancer, antioxidant, and catalytic activities of green synthesized gold nanoparticles using avocado seed aqueous extract
(American Chemical Society, 2023)Disposal of agricultural waste has a negative impact on the environment and human health and may contribute to the greenhouse effect. The field of nanotechnology could provide alternative solutions to upcycle agricultural ... -
Anticorrosion coated stainless steel as durable support for C-N-TiO2 photo catalyst layer
(MDPI, 2020)The development of durable photocatalytic supports resistant in harsh environment has become challenging in advanced oxidation processes (AOPs) focusing on water and wastewater remediation. In this study, stainless steel ... -
Antimicrobial activities of a novel biflavonoid and other constituents from Rhus natalensis
(Academic Journals, 2013)Phytochemical studies on Rhus natalensis root bark collected from Kenya led to the isolation and identification of a new biflavonoid (3-(1-(2,4-dihydroxyphenyl)-3,3-bis(4-hydroxyphenyl)-1-oxopropan-2- yl)-7-methoxy-4H-ch ... -
The antimicrobial activity of biogenic silver nanoparticles synthesized from extracts of Red and Green European pear cultivars
(Taylor & Francis, 2021-01)Green nanotechnology stands amongst the leading giants of innovation for the twenty first century technological advances. More interesting, is the use of natural products as reducing agents. These could be recyclable ... -
Antimicrobial activity of the secondary metabolites isolated from a South African red seaweed, laurencia corymbosa
(MDPI, 2023)South Africa’s highly diverse marine biota includes several endemic marine red algae of the Laurencia genus. Cryptic species and morphological variability make the taxonomy of Laurencia plant challenging, and a record of ... -
