A polypyrrole-chitosan-calcium ferrite nanocomposite was prepared using the electrodeposition method. The prepared layer was characterized by using Fourier transform infrared spectroscopy, the X-ray diffraction technique, and field emission electron microscopy. The thickness of the thin layers was in the range of 2.8 nm to 59.5 nm, and the refractive index of the composite layer was in the range of 1.66131+0.156i to 1.62734+0.167i. Detection and removal of cationic and anionic dyes, such as methylene blue and methylene orange, are subject of great interest for protecting environmental water. The layer composite was used to detect methylene orange and methylene blue using the surface plasmon resonance technique. Consequently, the polypyrrole-chitosan-calcium-ferrite composite layer interacted with the anionic and cationic dyes. The resonance angle shift for the detection of the cationic dye was larger than the resonance angle shift for the anionic dye. The sensor limit was achieved from a sensogram at about 0.01 ppm.

Pergeseran sudut surface plasmon resonance (SPR) pada konfigurasi Kretschmann-perak termodifikasi oleh nanopartikel cobalt ferrite (CoFe2O4) telah dikaji secara eksperimen di bawah pengaruh medan magnet. Tiga sampel nanopartikel CoFe2O4 dengan ukuran partikel yang berbeda, yaitu 1,68 nm untuk sampel A; 1,95 nm untuk sampel B; dan 5,87 untuk sampel C, disintesis dengan metode kopresipitasi. Pendeposisian tiga sampel menggeser sudut SPR referensi (prisma/Ag) dengan nilai yang berbeda-beda, yaitu sebesar 0,10°; 0,10°; dan 0,30°, dengan ketidakpastian masing-masing sebesar ±0,05° untuk sampel A, B, dan C secara berturut-turut. Setelah dikenai medan magnet luar,sudut SPR bergeser lagi sejauh 0,30° untuk sampel A dan B, dan 0,5° untuk sampel C, dengan ketidakpastian masing-masing sebesar ±0,05°. Selain itu, perbedaan dua arah medan magnet terkonfirmasi bahwa pergeseran sudut SPR memiliki nilai yang berbeda, yaitu 0,3°±0,05° dan 0,6°±0,05°. Respon nanopartikel CoFe2O4 pada pergeseran sudut SPR memberikan potensi sebagai smart materials pada sistem SPR

The issue of micro-plastics is becoming more and more important due to their ubiquity and the harm they cause to the human body. Therefore, evaluating the biological–physical interaction of micro-plastics with health cells has become the focus of many research efforts. This study focuses on the movement mode and low concentration detection development for micro-plastics in surface plasmon resonance (SPR). Firstly, 20-micrometer micro-plastics were prepared by grinding and filtering, and the movement mode was explored; then, the characteristics were investigated by SPR. Chromatographic analysis showed that the surface charge of micro-plastics dominated the elution time, and estrogen receptors (ERs) played a supporting role. A difference of micro-plastics in SPR sensorgram was observed, inferring the micro-plastics’ movement in rolling mode on the ERs. Characteristics analysis indicated that the low particle number of micro-plastics on SPR showed a linear relationship with the response unit (RU). When ERs were immobilized on the biosensor, the force of the binding of micro-plastics to ERs under an ultra-low background was equivalent to the dissociation rate constant shown as follows: PS (0.05 nM) > PVC (0.09 nM) > PE (0.14) nM). The ELISA-like magnetic beads experiment verified the specificity between ERs and micro-plastics. Therefore, by using the SPR technique, a biological-derived over-occupation of PS was found via higher binding force with ERs and longer retention time. In the future, there will be considerable potential for micro-plastics issues, such as identification in natural samples, biomarking, real-time detection in specific environments/regions and human health subject.
