Colloidal aggregates of small molecules are the most common artifact in early drug discovery, sequestering and inhibiting target proteins without specificity. Understanding their structure and mechanism has been crucial to developing tools to control for, and occasionally even exploit, these particles. Unfortunately, their polydispersity and transient stability have prevented exploration of cer...

The paper reviews recent experimental results concerning a wide variety of magnetic nanofluids with high saturation magnetization. Magnetic, rheological and magneto-rheological properties are presented and discussed, especially related to nanostructural processes and colloidal stability in applied magnetic field.

Multiplex optical coding carriers for biological assays have been achieved by coating silica colloidal crystals beads with quantum dots, which provided high stability, large capacity and simplicity for practical application.

Kinetic and thermodynamic studies reveal that the property of significantly enhanced catalytic activity with colloidal stability is attributed to an efficacious means of tuning enzyme-substrate association by varying with the rate constants in the presence of functionalized gold nanoparticles.

PAPER V. Gubala et al. Controlling colloidal stability of silica nanoparticles during bioconjugation reactions with proteins and improving their longer-term stability, handling and storage Despite the potential of antibody-coated nanoparticles (Ab-NPs) in many biological applications, there are very few successful, commercially available examples in which the carefully engineered nanomaterial h...

In this work the colloid stability mechanisms of two sulfonated latexes prepared by different methods are studied. One of the latexes (JM1) was prepared by surfactant-free emulsion copolymerization of styrene (St) and sodiun styrene sulfonate (NaSS), while the second latex (SN9) was prepared by a twostage “shot-growth” emulsion polymerization process using NaSS as ionic comonomer, which is incl...

Abstract Synthesis of silver nanoparticles was successfully synthesized by a chemical reduction method using nitrate (AgNO 3 ) as precursor and sodium borohydride (NaBH 4 reducing agent. The optical properties were studied based on their surface plasmon resonance (SPR) phenomenon UV-Visible spectrophotometry. absorbance spectra colloidal show the peak at wavelength range 380 nm to 450 nm. Collo...

A superoxide dismutase mimicking nanocomposite of remarkable functional and colloidal stability was developed by sequential adsorption polyelectrolytes metal complexes on nanoclay particles.
