Controlling the reversible thermochromism of polydiacetylene/zinc oxide nanocomposites by varying alkyl chain length

Colorimetric detection of influenza A (H1N1) virus by a peptide-functionalized polydiacetylene (PEP-PDA) nanosensor

“…3). [49][50][51][52][53] As the temperature increased, the dynamics of all segments within the PDA nanosensors increased, resulting in a shi in the absorption spectrum to a high-energy region and a change in the color transition from blue to red due to conformational change. As shown in Fig.…”

Biosafe, Renewable, and Optically Active Diacids Containing Amino Acid as Coupling Agents for the Modification of ZnO Nanoparticles

“…Also, peaks at around 1400 cm ¡1 were attributed to À ÀCOO, resulting from the formation of ester bond (Figure 1b 1619 cm ¡1 , which may exist in the form of COO ¡ that it can be due to the presence of ionic interaction between the carboxylate head of DA and Zn-OH 2 C at the surface of ZnO NPs. [30][31][32] These results indicated that -COOH group of DA has reacted with -OH on the surface of ZnO and ZnO NPs were modified successfully. Figure 3 showed the XRD patterns of bare and DA-coated ZnO NPs.…”

Nanostructured ZnO Materials: Synthesis, Properties and Applications

“…5.15). As hosting matrices, common polymers such as polymethylmethacrylate [229], polystyrene [230], poly(vinylalcohol) [231], and epoxy resins [232,233] as well as specialty polymers such as polynorbornene [234], polyacrylamide [235], polydiacetylene [236], and MEh-PPV copolymers [237] were used. A recent review of hybrid organic-inorganic light-emitting devices was reported by Sessolo and Bolink [238].…”
