Article Synopsis
  • Researchers developed a new fiber-optic sensor that effectively measures the refractive index (RI) of liquids using femtosecond laser writing on a special fiber structure.
  • The sensor achieves high sensitivity, detecting changes in RI with a wavelength shift of 161.40 nm per refractive index unit over a wide range.
  • This innovative device is easy to manufacture and offers precise measurements, making it suitable for applications in chemistry and biotechnology.

Coating superparamagnetic iron oxide NPs with SiO has been established in order to confer stability in acidic media. Acid stability tests were carried out between pH 1 and pH 7 to determine the effectiveness of the SiO passivating layer to protect the magnetic FeO core. Transmission Electron Microscopy (TEM) and zeta potential measurements have shown that uncoated FeO NPs exhibit rapid agglomeration and dissolution when exposed to acidic media, moving from a zeta potential of - 26 mV to a zeta potential of + 3 mV.
