Multifunctional, biocompatible and pH-responsive carbon nanotube- and graphene oxide/tectomer hybrid composites and coatings

Functionalization of Silver Nanowire Transparent Electrodes with Self-Assembled 2-Dimensional Tectomer Nanosheets

“…As we reported recently, carboxylated CNTs extensively interact with tectomers forming stable inks in aqueous solutions due to the favorable electrostatic interactions between them. In contrast, pristine unfunctionalized CNTs are not able to form hybrids with the tectomer . On the other hand, hydrogen bonding between oxygen functional groups in graphene oxide is responsible for their strong interaction with tectomers.…”

“…In contrast, pristine un-functionalized CNTs are not able to form hybrids with the tectomer. 39 On the other hand, hydrogen bonding between oxygen functional groups in graphene oxide is responsible 9 for their strong interaction with tectomers. Additional control of the tectomer assembly on a supporting substrate can be achieved through covalent functionalization of the tectomers' terminal amino groups.…”

“…pH values of solutions were measured using a Crison Basic 20 pH meter. pH values in water depend on oligoglycine concentration, due to the presence of HCl from oligoglycine synthesis; , thus, for the final 1, 0.5, and 0.01 mg mL –1 2T solutions, pH was 5.6, 5.8, and 6.3, respectively.…”

“…29 The exceptional structural and chemical features of tectomers have already been successfully utilized to coat negatively-charged surfaces, 30 biological membranes, 35 and polymer fibers, 36 and hold a promising potential in the field of antiviral applications. [37][38] Previously we showed, for the first time, that tectomers effectively coat carboxylated carbon nanotubes (CNTs) and strongly interact with graphene oxide and can be used for scaffolds in tissue engineering 39 as well as pH responsive nanocarriers for theranostics. 29 This paper is focused on establishing a fundamental understanding of the interactions between AgNWs and tectomers.…”

Self-Assembling Peptides and Carbon Nanomaterials Join Forces for Innovative Biomedical Applications

“…Alternatively, the amphiphilic nature of self-assembling peptides can be convenient to enhance carbon nanomaterials’ dispersibility in water [ 66 , 98 , 99 ]. Ordered oligoglycines, for instance, were shown to coat oxidized CNTs or GO thanks to non-covalent interactions between the carboxylic acid groups on the carbon nanomaterials and the N-terminus of the peptides, with potential applications in conductive tissue regeneration [ 100 ].…”
