The main purpose of this work was to obtain durable antimicrobial cotton textiles functionalized with l-cysteine (Cys) and silver nanoparticles (Ag NPs). Cys molecules were covalently linked to cotton fibers via esterification with the cellulose hydroxyl groups, and the Ag NPs tightly adhered to the fiber surface via coordination bonds with the Cys thiol groups. As a result, the Ag NPs coating on...
In the present work, we demonstrate a novel surface design by combination of benzoylecgonine (BE) antibody and poly-l-phenylalanine bearing electroactive macromonomer (EDOT-BTDA-PPhe). This system served as an electro-immunosensor platform for the analysis of cocaine use by detecting both BE and cocaine. To construct the immunosensor, a glassy carbon electrode was covered with EDOT-BTDA-PPhe. Subsequently,...
Affinity-type sensors have emerged as outstanding platforms in the detection of diagnostic protein markers, nucleic acids and drugs. Thus, these novel platforms containing antibodies could be integrated into the monitoring systems for abused drugs. Herein, we established a novel detection platform for the analysis of a common illicit drug; methamphetamine (METH). Initially, a fluorescent-labeled polypeptide...
We have reported the synthesis of mesoporous titania with crystalline walls using hexadecyltrimethylammonium bromide (CTAB), a typical cationic surfactant, as a template and titanium sulfoxide as a reactant in aqueous solution (Shibata et al., 2005 [1]). In this study, the removal method of CTAB from the mesopores without calcination or collapsing the ordered porous structure is described. First,...
