In this present study the bioconjugated fluorescent silica nanoparticles give an efficient fluorescent-based immunoassay for the detection of pathogen. The synthesized silica nanoparticles were polydispersed and the size of the silica nanoparticles was in the range of 114–164 nm. The energy dispersive X-ray spectrophotometer showed the presence of silica at 1.8 kev and the selected area diffractometer showed amorphous nature of silica nanoparticles. The FTIR spectrum confirmed the attachment of dye and carboxyl group onto the silica nanoparticles surface. The fluorescent silica nanoparticles showed highly efficient fluorescence and the fluorescent emission of silica nanoparticles occurred at 536 nm. The SEM image showed the aggregation of nanoparticles and bacteria. The growth of the pathogenicE. coliwas controlled using silica nanoparticles; therefore silica nanoparticles could be used in food packaging material, biomedical material, and so forth. This work provides a rapid, simple, and accurate method for the detection of pathogen using fluorescent-based immunoassay.

Smart water injection in oil and gas reservoirs is one of the most popular and low-cost methods to increase the recovery factor of reservoirs. However, due to the abundance of sandstone reservoirs in the world and the necessity to increase recovery in these types of reservoirs, injection of smart water will disturb the distribution of intergranular stresses in the porous media which results in sand production that causes many problems in many parts of the petroleum industry. For this reason, the necessity to investigate possible parameters affecting sand production was increased. Also, according to the relative researches, the injection of smart water changes the reservoir pH, which could change the sand production rate. In this paper, a comprehensive study on the effect of pH or alkalinity on sand production, as well as the effect and mechanism of silica nanoparticles, has been performed to control the grains separated from the rock. The effect and mechanism of silica nanoparticles with economic concerns have also been analyzed, which can significantly reduce and control the amount of sand production. In this paper, we can determine the effectiveness and the most effective parameters in an acidic or basic environment.

Major progress in the field of regenerative medicine is expected from the design of artificial scaffolds that mimic both the structural and functional properties of the ECM. The bionanocomposites approach is particularly well fitted to meet this challenge as it can combine ECM-based matrices and colloidal carriers of biological cues that regulate cell behavior. Here we have prepared bionanocomposites under high magnetic field from tilapia fish scale collagen and multifunctional silica nanoparticles (SiNPs). We show that scaffolding cues (collagen), multiple display of signaling peptides (SiNPs) and control over the global structuration (magnetic field) can be combined into a unique bionanocomposite for the engineering of biomaterials with improved cell performances.
