N,N,-Diethyl-m-Toluamide (DEET) Suppresses Humoral Immunological Function in B6C3F1 Mice [PDF]
Toxicological Sciences, 2009 N,N-diethyl-meta-toluamide (DEET) is a particularly effective broad-spectrum insect repellent used commonly in recreational, occupational and military environments. Due to its widespread use and suggested link to Gulf War Illness, this study examined the immunotoxicity of DEET.

Pest Management Science, EarlyView.Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Insect Molecular Biology, EarlyView.Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Validation and Mechanistic Studies of the Headspace Effect in MOF Synthesis
Angewandte Chemie, Volume 137, Issue 12, March 17, 2025.For a fixed vessel volume, the rate of metal–organic framework formation is shown to depend on the amount of solution employed. This headspace effect is demonstrated to arise only in the presence of oxygen. Mechanistic studies demonstrate that oxygen reacts with the formamide solvent and contributes to nitrosamine side products.
