This study is based on green synthesized nanomaterials that increase fluorescence intensity in the study of the anticancer drug palbociclib. The basis for the nanomaterials was the use of alumina/nickel oxide nanocomposite (alumina/NiO NCS) biogenically produced from millet seed extract. The proposed materials improved the spectrofluorimetric method for the study of the breast cancer drug palbociclib (PAL) in its real powder and capsules. The amplification properties of the developed spectrofluorimetric system depend on the unique optical properties of the alumina/NiO NCS. Fluorescence detection was determined at λex 260 and at λem 430 nm. The effect of surfactant (sodium dodecyl sulfate, SDS) was investigated, and the results obtained with the PAL alumina/NiO/SDS showed linearity of 1.0–800 g/mL for PAL samples with a correlation coefficient of r>0.999. The aforementioned fluorescence approach showed lower detection and quantification of 0.03 and 1.0 g/mL, respectively. The proposed system was potentially efficient for the determination of PAL with an excellent percent recovery of 99.50±0.5 %. The effect of some co‐formulated interfering substances such as crystalline cellulose, starch, silicon dioxide magnesium stearate, lactose and gelatine that present in the capsules was investigated and no remarkable difference was found during the assay process of PAL. The method was validated to ensure its suitability and showed high sensitivity and accuracy for the detection of PAL.

The short hole diffusion length (HDL) and high interfacial recombination are among the main drawbacks of semiconductor-based solar energy systems. Surface passivation and introducing an interfacial layer are recognized for enhancing HDL and charge carrier separation. Herein, we introduced a facile recipe to design a pinholes-free BiVO4 photoanode with a NiV2O6 back contact interfacial (BCI) layer, marking a significant advancement in the HDL and photoelectrochemical activity. The fabricated BiVO4 photoanode with NiV2O6 BCI layer exhibits a 2-fold increase in the HDL compared to pristine BiVO4. Despite this improvement, we found that the front surface recombination still hinders the water oxidation process, as revealed by photoelectrochemical (PEC) studies employing Na2SO3 electron donors and by intensity-modulated photocurrent spectroscopy measurements. To address this limitation, the surface of the NiV2O6/BiVO4 photoanode was passivated with a cobalt phosphate electrocatalyst, resulting in a dramatic enhancement in the PEC performance. The optimized photoanode achieved a stable photocurrent density of 4.8 mA cm–2 at 1.23 VRHE, which is 12-fold higher than that of the pristine BiVO4 photoanode. Density Functional Theory (DFT) simulations revealed an abrupt electrostatic potential transition at the NiV2O6/BiVO4 interface with BiVO4 being more negative than NiV2O6. A strong built-in electric field is thus generated at the interface and drifts photogenerated electrons toward the NiV2O6 BCI layer and photogenerated holes toward the BiVO4 top layer. As a result, the back-surface recombination is minimized, and ultimately, the HDL is extended in agreement with the experimental findings.
