Facile Route

FeS nanoparticles with uniform size have been prepared through a facile route using (sodium carboxymethyl cellulose) CMC as soft template. The nanoparticles are about 4-6 nm by observation of transmission electron microscopy (TEM). The CMC template could also stabilize the FeS nanoparticles and resist aggregation. It is important to note that the size of nanoparticles can be easily controlled by the concentration of iron and sulfur source during the synthetic process. Interestingly, the FeS nanoparticles could assemble into rod-like morphology at higher concentration. More importantly, the CMC-stabilized FeS nanoparticles exibit enhanced performance for Cr(Ⅵ) removal as compared with FeS synthesized without CMC stabilizer.

Materials modification with surface functional group for bioactive film or sensor surface is important in many applications. A suitable surface for each system can be shown high efficiency of detection. In this work, two different surfaces via covalent binding are created on gold substrate for finding the suitable surface in medical applications. The liver cancer biomarker, alpha-fetoprotein (AFP) was detected on two surfaces; one is carboxy dextran and another is a modified polymethyl metacrylate (PMMA). The substrates were improved by physical and chemical binding for AFP antibody immobilization. Contact angle and surface Plasmon resonance (SPR) were used to study the characteristic of surfaces. The result was found that the carboxy dextran gave higher detection than PMMA. Moreover, the dextran surface was studied in real serum samples. It was shown the significantly different between positive and negative AFP serum which is preliminary results for testing in more clinical samples further.
