Data on copper level in the blood of patients with normal and abnormal angiography

Abstract

In this data article, we measured the levels of copper in the blood of patients undergoing coronary angiography. The samples were taken from patients with cardiovascular disease in Bushehr׳s university hospital, Iran. Patients were divided in two groups: normal angiography and abnormal angiography. After the chemical digestion of samples, the concentration levels of Cu in both groups were determined by using inductively coupled plasma optical spectrometry (ICP-OES).

Colorimetric detection of Cu2+ based on the formation of peptide–copper complexes on silver nanoparticle surfaces

“…It is highly desirable to establish a system based on visual and spectral detection of Cu 2+ in water at concentrations below the safe limit for drinking water of 20 and 30 µM set by the US Environmental Protection Agency and the World Health Organization [ 5 , 26 ], and below the normal blood concentration of Cu 2+ , which is in the range of 24–135 µg/dL [ 27 ]. The interaction of Cu 2+ with the peptide ligands on the AgNP surfaces attracts neighboring AgNPs, which is observed as a color change from yellow to red.…”
