Photoelectrochemical sensing for hydroquinone based on porphyrin-functionalized Au nanoparticles on graphene.

Yaqi Hu et al.

Biosensors & bioelectronics, 47, 45-49 (2013-04-03)

A novel light "on-off" photoelectrochemical sensing for the sensitive determination of hydroquinone was developed based on the porphyrin-functionalized Au nanoparticles on graphene (porphyrin/AuNPs/graphene). Gold nanoparticles (AuNPs) were firstly modified onto graphene sheets using NaBH4 as reductant and the porphyrin/AuNPs/graphene nanocomposites

Effect of the benzene metabolite, hydroquinone, on interleukin-1 secretion by human monocytes in vitro.

P Carbonnelle et al.

Toxicology and applied pharmacology, 132(2), 220-226 (1995-06-01)

Decreased interleukin-1 (IL-1) production by mononuclear phagocytes has been shown to contribute to benzene myelotoxicity in animals. The study presented here was designed to examine the relevance of this mechanism in humans. Fresh human blood monocytes were exposed to 0.001-10

The safety of hydroquinone: a dermatologist's response to the 2006 Federal Register.

Jacob Levitt

Journal of the American Academy of Dermatology, 57(5), 854-872 (2007-05-01)

Recently, the US Food and Drug Administration proposed a ban on over-the-counter hydroquinone mainly on the basis of high absorption, reports of exogenous ochronosis in humans, and murine hepatic adenomas, renal adenomas, and leukemia with large doses over extended time
