Toward a smart optical biosensor based on nanoporous anodic alumina (NAA): by modifying the pore geometry in nanoporous anodic alumina we are able to change the effective medium at will and tune the photoluminescence of NAA. The oscillations in the PL spectrum are converted into exclusive barcodes, which are useful for developing optical biomedical sensors in the UV-Visible region.

Photonic crystals (PC) play a key role in optical field modulation due to their unique photonic band gaps (PBGs). Anodic aluminum oxide (AAO) prepared by pulse anodization is a promising candidate for PC devices. In this research, an AAO-based PC with multi-band was fabricated on a single-slice & single-material film, which exhibits multi-band responses in the visible-to-near-infrared (vis-NIR) region.

Article Synopsis
- A novel technique was developed to convert aluminum into transparent aluminum oxide through a small-scale anodization process using droplets.
- Anodization at 2 V for 10 minutes produced a uniform and transparent oxide layer, with chemical analysis showing the presence of aluminum oxide/hydroxide.
- The process resulted in a smoother surface and randomly distributed nanopores, indicating potential for broader applications in sustainable electronics and other fields.

Fluorescence fluctuation spectroscopy experiments were conducted to better understand the complex mass transport dynamics of organic molecules in liquid-filled nanoporous media. Anodic aluminum oxide (AAO) membranes incorporating 10 and 20 nm diameter cylindrical pores were employed as model materials. Nile red (NR) dye was used as a fluorescent tracer.

Preeclampsia is a pregnancy-specific hypertensive syndrome recognized as the leading cause of maternal and fetal morbidity worldwide. Early diagnosis is crucial for mitigating its adverse effects, and recent investigations have identified endoglin as a potential biomarker for this purpose. Here, we present the development of a hybrid biosensor platform for the ultrasensitive detection of endoglin, aimed at enabling the early diagnosis of preeclampsia.
