A mixed matrix membrane (MMM), based on carbon nanotubes (CNTs) and hollow fiber (HF), was prepared and combined with solid phase microextraction (SPME) mode to determine strychnine and brucine in urine. This MMM was prepared by dispersing CNTs in water via surfactant assistance, and then immobilizing CNTs into the pores of HF by capillary forces and sonification. The prepared carbon nanotubes reinforced...
A novel design of carbon nanotubes reinforced hollow fiber solid/liquid phase microextraction (CNTs-HF-SLPME) was developed to determine piroxicam and diclofenac in different real water samples. Functionalized multi-walled carbon nanotubes (MWCNTs) were held in the pores of hollow fiber with sol–gel technology. The pores and lumen of carbon nanotubes reinforced hollow fiber were subsequently filled...
Novel fluorescent YVO 4 :Eu nanocrystals were ∼15nm in diameter and had been functionalized with phosphorous polyacrylic acids at the surface during the synthesis, which illuminated their potential in bioassays. In this paper, bovine serum albumin (BSA) was covalently coupled to activated nanocrystals from primary amine groups by EDC and sulfo-NHS chemistry successfully. Reaction condition,...
