A hapten-protein conjugate for determining carbaryl using copper nanoparticles was first synthesized in the present work. The were used as electrochemical labels direct solid-phase competitive analysis of residues flour from some crops. Copper stabilized by chitosan and a with UV/VIS - spectroscopy, transmission electron microscopy, dynamic light scattering are characterized. To form recognitio...

The influence of the sensitive element fabrication technology and noise performance of surface plasmon resonance (SPR) immunosensor on sensitivity and stability of operation inherent to the “Plasmon” series instrument has been investigated to improve reliability of diagnosis and treatment of the Epstein–Barr herpes virus disease. To minimize the effect of the temperature change induced noise, c...

Acquired immune deficiency syndrome (AIDS) is a severe communicable immune deficiency disease caused by the human immune deficiency virus (HIV). The analysis laboratory diagnosis of HIV infection is a crucial aspect of controlling AIDS. The p24 antigen, the HIV-1 capsid protein, is of considerable diagnostic interest because it is detectable several days earlier than host-generated HIV antibodi...

Study of biophysical interactions have been carried out using specific combination of proteins such as Brucella abortus cell envelop protein (as antigen) and its complementary antibody (raised in mice and rabbit). A best optimized composition of biocompatible CeO2 nano-octahedra and other biocompatible materials (chitosan) was used in this study. Linear range was found in the range of 6.25 μg/m...

UNLABELLED A highly sensitive label-free immunosensor for the detection of HIV-1 is newly developed based on localized surface plasmon resonance (LSPR) method. Uniform nanopattern of circular Au-dots (10-20nm) was fabricated on indium tin oxide (ITO) coated glass substrate by simple electrochemical deposition method. The surface of Au nanopattern was modified with HIV-1 neutralizing gp120 monoc...

A simple and novel supramolecular hydrogel was prepared from ferrocene (Fc) modified amino acid phenylalanine (F) and utilized as electrochemical immunosensing platform for the detection of human IgG. Scanning electron microscopy (SEM) characterization indicated that the hydrogel is composed of fibrils with diameter around 50-100 nm and length extend to 1mm. When the prepared hydrogel was react...
