This paper demonstrates a previously unreported property of deoxyribonucleic acid-the ability of dye-labeled. solid-state DNA dried onto a surface to detect odors delivered in the vapor phase by changes in fluorescence. This property is useful for engineering systems to detect volatiles and provides a way for artificial sensors to emulate the way cross-reactive olfactory receptors res... https://parisnaturalfoodes.shop/product-category/ester-c-250mg-orange/
