Malaria, a mosquito-borne disease caused by the Plasmodium species, claims more than 400,000 lives globally each year. Increasing drug resistance of the parasite renders the development of new anti-malaria drugs necessary. Alternatively, better delivery systems for already marketed drugs could help to solve the resistance problem. Herein, we report glucose-based ultra-small gold nanoparticles (Glc-NCs) that bind to cysteine-rich domains of Plasmodium falciparum surface proteins.

Malaria represents one of the most common infectious diseases which becoming an impellent public health problem worldwide. Antimalarial classical medications include quinine-based drugs, like chloroquine, and artesunate, a derivative of artemisinin, a molecule found in the plant Artemisia annua. Such therapeutics are very effective but show heavy side effects like drug resistance. In this study, "green" silver nanoparticles (AgNPs) have been prepared from two Artemisia species (A. abrotanum and A. arborescens), traditionally used in folk medicine as a remedy for different conditions, and their potential antimalarial efficacy have been assessed.

Malaria is a worldwide serious-threatening infectious disease caused by Plasmodium and the parasite resistance to antimalarial drugs has confirmed a significant obstacle to novel therapeutic antimalarial drugs. In this article, we assessed the antioxidant and anti-inflammatory activity of nanoparticles prepared from Indigofera oblongifolia extract (AgNPs) against the infection with Plasmodium chabaudi caused in mice spleen.

Not Open Access | Biosynthesized silver nanoparticles protect against hepatic injury induced by murine blood-stage malaria infection

Biosynthesized nanoparticles proposed to have antiplasmodial activities have attracted increasing attention for malaria that considered being one of the foremost hazardous diseases. In this study, Indigofera oblongifolia leaf extracts were used for the synthesis of silver nanoparticles (AgNPs), which were characterized utilizing transmission electron microscopy.

NOT Open Access | 22 factorial design-based biocompatible microneedle arrays containing artemether co-loaded with lumefantrine nanoparticles for transepidermal delivery
