“…387 CuNCs prepared directly from chicken egg white (CEW) demonstrated pH reversible features mostly ascribed to conformational changes of ovalbumin protein in CEW upon pH variations from acidic to basic. 388 Furthermore, the intense green emission can be observed in strong basic conditions, whereas at lower and mostly in acidic buffers the PL decreased, consistent with precipitation of the CuNCs.…”

“…The sensor showed great stability up to two months. (Qiao et al, 2015) Aparna et al have used polyethylene imine capped copper nanoclusters for trinitrotoluene (TNT) colorimetric and fluorescent detection. Nanoclusters were synthesized by a one-pot microwave method and showed a blue emission at 480 nm.…”

Copper is an important metal in analytical and industrial fields as it has excellent thermal and electrical properties. In many disciplines, like electronics, optics, and others, copper nanoforms pay more attention than other noble metals nanoparticles. Attractive are its natural abundance, low costs and high activity toward many analytes with simultaneous physical stability. Extensive use has brought new types of sensors and practical implementations. The objective of this paper is to present crucial developments of copper material in the sensing field. Practical applications in the environmental section, like chemical oxygen demand measurement or carbon dioxide reduction reaction for atmospheric CO2 reduction; technological sensors like organic light-emitting devices, electronic tongue for alcohol type determination, human skin touch and move sensor; and medical sensors for glucose, alcohol, dopamine or paracetamol detection were presented.

“…As a typical experiment, 37 the CEW was prepared by carefully separating the white portion of the chicken egg from the whole fresh egg, followed by freeze drying; the obtained solid dry white powder was used as such without any further purification. The CEW-Au NCs were synthesized based on a reported method 6 with slight modification.…”

In this paper, chicken egg white purchased from a local market without further purification was directly used to prepare fluorescent gold nanoclusters through a one-step, simple, fast and green synthesis approach for analytical purposes. The as-prepared chicken egg white stabilized gold nanocluster probe has strong red fluorescence emission, which can be quenched by mercury ions and copper ions sensitively. By using an ethylenediaminetetraacetate (EDTA) masking method, mercury ions in the range from 0.60 to 10 μM can be linearly detected with the limit of detection (LOD, 3σ) of 0.510 μM in the presence of equivalent copper ions. Since the preparation of a chicken egg white stabilized gold nanocluster probe is fast, easy and cheap, this selective analytical method for mercury pollution monitoring in environmental waters may be widely used in daily life by ordinary people.
