Monitoring of Anthracene Using Nanoscale Au-Cu Bimetallic Alloy Nanoparticles Synthesized with Various Compositions.

Bimetallic alloy Au-Cu nanoparticles (Au-Cu alloy NPs) were synthesized using a chemical reduction method for sensing applications. Electronic absorption spectroscopy (UV-visible spectroscopy), X-ray diffraction (XRD), and scanning electron microscopy (SEM) were used for the confirmation and morphological studies of the synthesized nanoparticles. The composition of Au-Cu alloy NPs was studied by energy-dispersive spectroscopy (EDS).

Mucosal lichen planus simultaneously involving oral mucosa, conjunctiva and larynx.

Lichen planus is an autoimmune disease that typically involves skin and the mucosa of the mouth and genitalia. The involvement of conjunctival and laryngeal is rare. A young patient presented with hoarseness of voice, oral ulcerative lesions and symblephron.
