Gold nanoparticles - against parasites and insect vectors

Area of Science:

• Biomedical Science
• Parasitology
• Entomology

Background:

• Nanomaterials, particularly gold nanoparticles (Au NPs), possess unique properties for biological applications.
• Au NPs are increasingly investigated for their potential in combating parasitic diseases and controlling insect vectors.

Purpose of the Study:

• To review the bioactivity of Au NPs against key insect vectors and parasites.
• To summarize the antiparasitic roles of Au NPs in various human and animal diseases.
• To explore the use of Au NPs in diagnostics and vaccine development.

Main Methods:

• Literature review of studies on gold nanoparticles' bioactivity.
• Analysis of research on Au NPs against mosquito vectors (Aedes aegypti, Anopheles stephensi, Culex quinquefasciatus).
• Review of Au NP toxicity against helminths (Schistosoma mansoni, Raillietina).

Main Results:

• Au NPs exhibit toxicity against selected insect vectors and helminths.
• Au NPs show antiparasitic effects against malaria, leishmaniosis, toxoplasmosis, trypanosomiasis, cryptosporidiosis, and microsporidian parasites.
• Au NPs have potential as biomarkers, diagnostic tools, and vaccine adjuvants.

Conclusions:

• Gold nanoparticles hold promise for developing novel strategies against parasitic diseases and vector-borne illnesses.
• Further research is crucial to understand the effects of Au NPs on diverse arthropod vectors and their ecotoxicological impact.
