In this study, the potentiality of Sulfonated-Oxidized activated carbon as an adsorbent for removing Methylene Blue (MB), Crystal Violet (CV), and Thionin Acetate (Th) from aqueous solutions was investigated. The characteristics of the synthesized adsorbent were examined by FTIR and SEM techniques. By changing experimental conditions like contact t...

The construction of graphene-based microfibers with reinforced mechanical and electrical properties has been the subject of numerous researches in recent years. However, the fabrication of graphene-based fibers with remarkable optical features still remains a challenge and has not been addressed so far. This paper aims to report a series of flexibl...

Engineering interparticle plasmon coupling through controlling the assembly of plasmonic NPs onto the surface of sacrificial substrates is quite promising for establishing inherently absent selectivity or sensitivity toward a particular analyte. Herein, we introduce a robust sensor array strategy based upon the assembly of gold nanoparticles (AuNPs...

Gold nanorods (AuNRs) have recently become fascinating chromophores in the field of colorimetric sensing because of their eye-catching rainbow colors along with the high dimensionality of their optical profile. The etching of AuNRs using an analyte-sensitive oxidizing agent is particularly an attractive tool not only for adjusting their plasmonic b...

The unique optical properties of plasmonic gold (Au) and silver Ag) nanoparticles (NPs) due to localized surface plasmon resonance (LSPR), surface modifications of Au and Ag NPs through non-covalent/covalent conjugations, and their applications in colorimetric detection of various ionic and neutral analytes are discussed in this chapter. The chapte...

This paper reports on the synthesis of a novel nanocomposite of multi-wall carbon nanotubes (CNTs), magnetite nanoparticle (Fe3O4), and polyethylenimine (PEI) to construct an electrochemical sensor for highly sensitive determination of ciprofloxacin (CIP) drug in biological samples and pharmaceutical formulations. The nanocomposite contains many am...
