“…Inorganic materials able to withstand harsh process conditions such as TiO2, ZnO, MgO, MMT, and CaO have attracted wide attention. Among them, ZnO nanoparticles (NPs) have been researched a lot because of their low price, unique physical properties brought by the size effect, and potential applications in UV blocking materials [7,8,9,10,11,12].…”

Herein, ZnO nanoparticles (NPs) were synthesized using zinc acetate and an amino hyperbranched polymer. The methods of transmission electron microscope (TEM) and X-ray Diffraction (XRD) were applied to the characterization of ZnO NPs. Polypropylene (PP)/ZnO fiber was prepared using 1–5 wt% ZnO NPs via melt spinning. The ultraviolet light (UV)-degradation behavior, antibacterial activity and mechanical properties of PP fibers were characterized. The PP fiber filled with ZnO NPs presents better mechanical properties and the resistance to UV light degradation. For the best effect, the contents of ZnO NPs were set 4 wt% in PP fiber. FTIR analysis shows significant photo-degradation of PP induced by UV irradiation and a remarkable reduction in the UV degradation of the fiber filled with ZnO NPs. It is also observed that the ZnO NPs-filled fiber has good antibacterial actives against Escherichia coli and staphylococcus aureus.

“…The diameter of the Debye diffraction ring reflects the particle spacing of the 2DPC 7 . Smart hydrogels are soft materials that can respond to external stimuli and generate volume phase transitions 8 . When a 2DPC array is embedded in a smart hydrogel, the particle spacing of the 2DPC will change after the hydrogel is exposed to an environment containing target analytes due to the hydrogel volume change induced by the external stimuli.…”

Smart photonic hydrogels based on two-dimensional photonic crystals (2DPC) provide a promising sensing platform for constructing novel chemical and biological sensors due to their facile optical signal readout and highly sensitive responsivity toward target analytes. Aptamers, as recognition elements with high selectivity and affinity, are extensively used to construct a variety of sensors. Herein, we developed two partially base complementary aptamer-functionalized 2DPC hydrogels as aptasensors for the detection of thrombin (TB) in human serum. The photonic hydrogel aptasensors swelled upon exposure to TB solution, leading to an increase in the particle spacing of the 2DPCs. The particle spacing changes were acquired by simply measuring the diameters of the Debye ring diffracted by the 2DPCs without the requirement of sophisticated instruments. The aptasensor swelling resulted from the decrease in the hydrogel cross-linking density induced by the specific binding between one of the aptamers and TB and the increase in hydrogel mixing free energy induced by the introduction of TB. The particle spacing increase of the optimized aptasensor was linear over the TB concentration range of 1–500 nM, and the limit of detection was 0.64 nM. The constructed 2DPC hydrogel aptasensor was used to detect TB in human serum and achieved recoveries of 95.74–104.21% and a relative standard deviation of 2.52–6.58%, showing the practicability and accuracy of the sensor. The aptamer-actuated 2DPC hydrogel biosensor provides a new strategy for designing other target molecule-sensitive aptasensors, showing great potential for development into home kits.
