Abstract In this study, sulfated β-cyclodextrin (S-β-CD) which is a β-cyclodextrin derivative was obtained by chemical treatment of natural β-cyclodextrin (β-CD) with sulfuric acid. Afterwards, β-CD and S-β-CD were applied to cotton fabrics. In different treatments, β-CD and S-β-CD were bonded to cotton fabrics with EDTA crosslinking agent. Then, all the fabrics were treated with antibacterial agent silver nanoparticles (AgNPs) and inclusion complexes were formed. The aims of this study were to increase the washing stability and the antibacterial activity against microorganisms and to compare the effects of β-CD complex and derivative complex with silver nanoparticles on treated cotton samples. So, for this purpose, the properties of the treated samples like antibacterial activity, washing stability, add-on, tensile strength, handle, thickness and color change were tested and compared to each other. In addition, characterization analyzes such as SEM, EDX and FT-IR were performed on the samples and XRD analysis was performed to characterize the AgNPs. As a result of the study, it was observed that AgNPs alone were not sufficient to obtain antibacterial textiles with strong antibacterial effect and good washing stability. The inclusion complexes formed with β-CD and S-β-CD had much more effective antibacterial activity and more robust washing stability. In addition, when the physical properties except stiffness and yellowness were considered besides antibacterial activity and washing stability, the treatment of derivative β-CD complex with AgNPs and crosslinking this complex to cotton sample by means of EDTA was found to be the most favorable method.

High Volatility

Although the insecticidal properties of some plant essential oils are well-documented, their use in integrated pest and vector management is complicated by their high volatility, low thermal stability, high sensitivity to oxidation, and low solubility in water. We investigated the use of bio-based N-1-hexadecylammonium chloride and sodium palmitate amylose inclusion complexes as emulsifiers for two essential oils, garlic and asafoetida, known to be highly toxic to mosquito larvae. Four emulsions of each essential oil based on amylose hexadecylammonium chloride and amylose sodium palmitate inclusion complexes were evaluated for their toxicity against Aedes aegypti L. larvae relative to bulk essential oils. All emulsions were significantly more toxic than the bulk essential oil with the lethal dosage ratios ranging from 1.09–1.30 relative to bulk essential oil. Droplet numbers ranged from 1.11 × 109 to 9.55 × 109 per mL and did not change significantly after a 6-month storage period. These findings demonstrated that amylose inclusion complexes enhanced the toxicity of essential oils and could be used to develop new essential oil based larvicides for use in integrated vector management.

Optic Probe

Surface-enhanced Raman Scattering (SERS) fiber probe provides abundant interaction area between light and materials, permits detection within limited space and is especially useful for remote or in situ detection. A silver decorated SERS fiber optic probe was prepared by hydrothermal method. This method manages to accomplish the growth of silver nanoparticles and its adherence on fiber optic tip within one step, simplifying the synthetic procedure. The effects of reaction time on phase composition, surface plasmon resonance property and morphology were investigated by X-ray diffraction analysis (XRD), ultraviolet-visible absorption spectrum (UV-VIS absorption spectrum) and scanning electron microscope (SEM). The results showed that when reaction time is prolonged from 4–8 hours at 180 °C, crystals size and size distribution of silver nanoparticles increase. Furthermore, the morphology, crystal size and distribution density of silver nanoparticles evolve along with reaction time. A growth mechanism based on two factors, equilibrium between nucleation and growth, and the existence of PVP, is hypothesized. The SERS fiber probe can detect rhodamin 6G (R6G) at the concentration of 10−6 M. This SERS fiber probe exhibits promising potential in organic dye and pesticide residue detection.
