In this study, we investigated the chemical functionalization of carboxylated multiwalled carbon nanotubes (MWCNT–COOH) by 1-Amino-2-naphthol-4-sulfonic acid (ANSA). The functionalized MWCNTs exhibited good aqueous solubility due to the presence of the –OH and – SO3H groups of ANSA. The antimicrobial activity of the MWCNT–COOH as well as its functionalized multiwall nanotube MWCNT-CO-2-(1-amino...

Bacteria can grow in different materials that are in close contact with humans, foods, etc., so, it is very important to control this matter in order to prevent risk of infections. Antimicrobial resistance (AMR) threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi. Multiwall carbon nanotubes (MWNTs) have inte...

multifunctional nanomaterials showed graet advantages in drug delivery. folic acid (fa) binding protein, a glycosyl phosphatidyl inositol anchored cell surface receptor for folate, is overexpressed in several human tumors, whereas it is highly restricted in normal tissues. therefore, in this study, fa, polyethylene glycol (peg), and fe3o4 nanoparticles multifunctionalized short multiwall carbon...

nanotechnology is the study of manipulating matter on an atomic and molecular scale. generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension size from 1 to 100 nanometers .  carbon nanotubes have great potentials for novel applications in industry, drug delivery system and many other uses. in this work after purification, multiwa...

A commercial multiwall carbon nanotube and its carboxylated derivate (CNTC and COOHC, respectively) was used after purification to study the competitive adsorption of phenol (P) and m-chlorophenol (CP) from 0.1 M aqueous NaCl solutions without external pH control. The adsorption takes place practically exclusively on the external surface of the nanotubes. The uptake of P is suppressed in compar...
