Abstract
Sol–gel-derived nanosilica materials covalently anchored by functionalized terbium complexes with different dimensions were prepared. Zero-dimensional hybrid had a diameter of 50 nm with regular spherical shape. The lengths and widths of 1D nanorod hybrid were in the range of 50–70 and 20–30 nm. The specific surface areas of the two-dimensional materials were 81 and 108 cm2/g, respectively. Both materials bind hemoglobin in aqueous buffer solution (pH 7.4) as shown by striking luminescence changes. These novel findings will pave the way for the application of novel nanostructured lanthanide hybrids in sensor devices.
