Abstract
Lysozyme is a well-known enzyme found in many biological fluids which plays an important role in the antibacterial protection of humans and animals. Lysozyme assays are used for the diagnosis of a number of diseases and utilized in immunohistochemistry, genetic and cellular engineering studies. The assaying methods are divided into two categories measuring either the concentration of lysozyme as a protein or its activity as an enzyme. While the first category of methods traditionally uses an enzyme-linked immunosorbent assay (ELISA), the methods for the determination of the enzymatic activity of lysozyme use either live bacteria, which is rather inconvenient, or natural peptidoglycans of high heterogeneity and variability, which leads to the low reproducibility of the assay results. In this work, we propose the use of a chemically synthesized substrate of a strictly defined structure to measure in a single experiment both the concentration of lysozyme as a protein and its enzymatic activity by means of the fluorescence polarization (FP) method. Chito-oligosaccharides of different chain lengths were fluorescently labeled and tested leading to the selection of the pentasaccharide as the optimal size tracer and the further optimization of the assay conditions for the accurate (detection limit 0.3 μM) and rapid (<30 min) determination of human lysozyme. The proposed protocol was applied to assay human lysozyme in tear samples and resulted in good correlation with the reference assay. The use of synthetic fluorescently labeled tracer, in contrast to natural peptidoglycan, in FP analysis allows for the development of a reproducible method for the determination of lysozyme activity.

Sensitive determination of lysozyme by using a luminescent and colorimetric probe based on the aggregation of gold nanoparticles induced by an anionic ruthenate(II) complex.

Abstract
The negatively charged ruthenate(II) complex [Ru(bpy)(PPh3)(CN)3]- and gold nanoparticles (AuNPs) were used for detecting lysozyme (LYS). The luminescence of the ruthenate(II) complex is quenched by AuNPs, and this induces the aggregation of AuNPs and a color change from red to blue. After addition of lysozyme, the positively charged lysozyme and the negatively charged ruthenate(II) complex bind each other by electrostatic interaction firstly. This prevents AuNPs from aggregation and quenches the emission of the ruthenate(II) complex. Its luminescence and the degree of aggregation of the AuNPs can be used to quantify LYS. The fluorometric calibration plot is linear in the 0.01 to 0.20 μM LYS concentration range, and the calibration plot is linear between 0.02 and 0.20 μM of LYS. The color of the solution can be easily distinguished by bare eyes at 0.08 μM or higher concentration of LYS. The applicability of the method was verified by the correct analysis of LYS in chicken egg white.

Abstract
A new method for determination of lysozyme with high sensitivity based on Resonance Rayleigh scattering (RRS) by using Au nanoparticles as a probe was proposed in this experiment. The RRS spectrum, nonlinear scattering (second-order scattering (SOS), frequency doubling scattering (FDS)) spectra and absorption spectrum of the Au nanoparticles-lysozyme system have been analyzed. In addition, the effects of several factors on scattering intensities were investigated, including pH value of solution, amount of Au nanoparticles, mixing sequence of each reagent and the coexisting substances. The results showed that the coexisting substances have little influence on the RRS intensities of the systems. Moreover, the possible mechanism for the RRS enhancement of Au nanoparticles-lysozyme system was preliminary discussed. The RRS method for determination of lysozyme has good sensitivity and selectivity with the detection limits 30.1 ng/ml. The contents of lysozyme were determined with recoveries of 98.2-105.4% and relativity relative standard deviation (RSD) of 0.3-3.7%, respectively. It proved that the method established in our study is suitable for the determination of lysozyme in synthetic sample and natural chicken egg white sample.

Abstract
CdHgTe nanoparticles (NPs) with the emission in the near-infrared regions were prepared in aqueous solution, and were characterized by transmission electron microscopy, X-ray diffraction spectrometry, spectrofluorometry and ultraviolet-visible spectrometry. Based on the fluorescence quenching of CdHgTe NPs in the presence of proteins, a novel method for the determination of proteins with CdHgTe NPs as a near-infrared fluorescence probe was developed. Maximum fluorescence quenching was observed with the excitation and emission wavelengths of 500 and 693 nm, respectively. Under the optimal conditions, the calibration graphs were linear in the range of 0.04 x 10(-6)-5.6 x 10(-6) g ml(-1) for lysozyme (Lyz) and 0.06 x 10(-6)-6.1 x 10(-6) g ml(-1) for bovine hemoglobin (BHb), respectively. The limits of detection were 13 ng ml(-1) for Lyz and 27 ng ml(-1) for BHb, respectively. Four synthetic samples were determined and the results were satisfied.
