“…As can be seen in Figure f1, the tightly packed nanoantennas are inclined to stick together, reducing the achievable RIS, FOM, and molecular sensitivity. It must be mentioned that Au directly deposited on top of the tubular PAA pores can also be used as an LSPR sensor. − …”

In the past couple of decades, the development of plasmonic nanosensors underwent rapid progress in the fields of fabrication, integration, and realized applications. Localized surface plasmon resonance imaging (LSPRi) promises the possibility of high-throughput biomolecule sensing integrated into miniaturized point-of-care devices. This paper aims to provide a critical review of the LSPRi-compatible sensor nanofabrication technologies and compare the most crucial characteristics of implemented LSPRi sensors, focusing on label-free nucleic acid detection. Besides the optimization of fabrication, a practical sensor needs meticulous design regarding the protocols used as well, and the challenging area of label-free DNA/RNA sensing thus provides a reasonable basis for benchmarking sensor capabilities. All previously reported LSPRi-compatible nucleic acid sensors are critically evaluated and compared based on their fabrication technologies (size and uniformity of the sensor area) and sensor performance (refractive index sensitivity, detection limit, and dynamic range). The most relevant factors to consider upon selection of a fabrication technology and the importance of proper DNA immobilization/hybridization conditions are also discussed in detail.

“…Various applications have been reported for NAA such as biosensors [ 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ], sensors [ 36 , 66 , 67 , 68 , 69 , 70 , 71 ], drug release [ 72 , 73 , 74 , 75 , 76 ], template-based nanowire, and nanotube fabrication [ 77 , 78 , 79 , 80 ]. Among the various sensors and biosensors that have been reported based on NAA, optical biosensors are the more interesting because of their remote sensing ability and properties such as being small and lightweight, having high sensitivity, and being immune to electromagnetic interference [ 81 , 82 , 83 , 84 , 85 , 86 ].…”

“…Up to now, several optical methods have been reported when using an NAA such as surface plasmon resonance (SPR) [ 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 ], interference localized surface plasmon resonance (ILSPR) [ 36 , 82 , 96 , 97 , 98 , 99 , 100 , 101 ], photoluminescence spectroscopy (PLS) [ 32 , 102 , 103 , 104 , 105 , 106 , 107 ], surface-enhanced Raman scattering (SERS) [ 84 , 108 , 109 , 110 , 111 , 112 , 113 , 114 ], and interferometric reflectance spectroscopy (IRS) [ 59 , 115 , 116 , 117 ]. Among them, IRS is a common optical method that has been applied as the basis for the NAA-based biosensors and sensors.…”

This review paper focuses on recent progress in optical biosensors using self-ordered nanoporous anodic alumina. We present the fabrication of self-ordered nanoporous anodic alumina, surface functionalization, and optical sensor applications. We show that self-ordered nanoporous anodic alumina has good potential for use in the fabrication of antibody-based (immunosensor), aptamer-based (aptasensor), gene-based (genosensor), peptide-based, and enzyme-based optical biosensors. The fabricated optical biosensors presented high sensitivity and selectivity. In addition, we also showed that the performance of the biosensors and the self-ordered nanoporous anodic alumina can be used for assessing biomolecules, heavy ions, and gas molecules.

“…Ito et al [11], Capraz et al [12] and Lee et al [13] state that the aluminum anodizing process is an electrochemical method to convert aluminum into aluminum oxide (Al 2 O 3 ) on the surface to be coated to produce a thicker oxide layer than the naturally formed oxide layer so as to improve the physical and mechanical properties of metals the. This can be achieved by making the workpiece as an anode which is then dipped in the appropriate electrolyte cell.…”

To determine the effect of sulfuric acid electrolyte concentration and the most optimal electrical potential during the anodizing process on the tensile strength of aluminum alloy 6061 T6. The anodizing process of aluminum alloy is carried out at different electrolyte concentrations, which are 10, 20 and 30% of the volume of sulfuric acid used. As a cathode, carbon rods are used. The duration of the process for each electrolyte concentration is 15 minutes, while the potential used is 10 V, 20 V and 30 V. The tensile testing process is carried out using a Universal Testing Machine and surface morphology is investigated using Scanning Electron Microscopy Phenom G2 Anodizing process using 20% sulfuric acid electrolyte concentration and 20 V potential has the highest ultimate tensile strength. However, on the surface morphology, the pore size starts to enlarge when compared to the potential and concentration of the electrolyte below. As for the potential and higher concentrations of sulfuric acid, there is a decrease in tensile strength and an increase in pore size. This can make an understanding concept of how AA 6061 T6 reacts to the tensile stress after anodizing process is carried out, so that it can later be applied to industry and machinery.
