The purpose of this paper is to present advanced techniques in optical biodevices. Moreover different configurations involving the generation of fiber optical biosensors are described. To overcome some limitations of fiber optical biosensors, plasmonic phenomena proposed. In addition novel plasmonic phenomena have broaden researcher’s horizons in new discovering in terms of technology and application. As regards there are many challenges to detect ultra-low concentration samples with high sensitivity in real time. Researchers have always made great efforts to discover more effective methods. Throughout the paper SPR and LSPR as a powerful analysis instrument are introduced. Finally surveys the current practical performances of plasmonic sensors in detection of bio target are provided. As a result these devices demonstrate great potential in identifying target analytic due to their unique optical biosensors.

“…Gold (Au) nanorods were synthesized by the seed meditated method as described [15]. Briefly, Au seed solution was prepared by diluting 0.25 ml 10 mM HAuCl 4 in 9.75 ml 0.1 M CTAB, and followed by injection of ice-cold 600 µl 10 mM NaBH 4 to the mixture of HAuCl 4 and CTAB at the stirring speed of 1000 rpm.…”

“…During the phase transition, p-NIPAAm hydrogel shows a reversible change in optical, physical, and chemical properties, which creates great interest in biomedical applications such as actuators [12], drug delivery [13], and tissue engineering [14]. By incorporating Au nanorods as dopants during the hydrogel synthesis, plasmonassisted heating can be utilized to remote control the reversible hydrogel properties [15]. Furthermore, the micrometer-scale hydrogel columns formed within pores allow fast reversible photothermal actuation.…”

Controlled photothermal actuation of liquid release is presented using periodically arrayed hydrogel columns in a macroporous silicon membrane. Thermo-responsive hydrogel is mixed with Gold (Au) nanorods, and surface plasmon-induced local heating by near-infrared (NIR) light is utilized as an actuation method. We adopted theoretical modeling, which treats the hydrogel as a poro-viscoelastic medium to understand the mechanical and liquid transport properties of the hydrogel. To demonstrate the feasibility of the liquid release control using NIR light, we first characterized the temperature response of Au nanorod embedded hydrogel in the silicon membrane using its optical transmission behavior to confirm the successful device fabrication. Next, the liquid release characteristics from the structure were studied using fluorescent imaging of fluorescein dye solution while pulsed NIR light was illuminated on the structure. We successfully demonstrate that the liquid release can be controlled using remote NIR illumination from the presented structure. Considering the periodically arrayed configuration with high spatial resolution, this will have a potential prospect for optically-addressable chemical release systems, which benefit retina prosthesis interfaces.

“…For many applications such as biosensors, chemical sensors, and catalysts, the recent developments in the carbonaceous material such as graphane, graphyne, and graphdiyne are the pioneers in the research field [29][30][31][32][33][34][35][36]. In addition, in recent years the detection of many different viruses was important for controlling disease spread [37][38][39][40][41]. According to molecular dynamics, Barraza-Lopez and Kaloni have been considered the water dissociation on the monolayer monochalcogenides of group IV, like phosphorene, GeS, GeTe, and GeSe [42][43][44][45][46][47].…”

In the current study, by employing first-principles computations, the adsorption behavior of letrozole (LET) was investigated on the pristine graphdiyne nanosheet (GDY) as well as Si-doped graphdiyne (SiGDY). According to the adsorption energy, charge transfer value, and the change in the bang gap energy, the tendency of the pristine GDY towards LET is insignificant. However, the interaction of LET with SiGDY was strong and the adsorption energy was approximately − 19.20 kcal/mol. In addition, the associated electrical conductivity with SiGDY increased by approximately 23.53 % following the adsorption of LET. The results show that SiGDY can be employed as an electronic sensor to detect LET. Furthermore, LET is detected by SiGDY in the water phase based on the magnitude of solvation energy. Finally, a considerable charge-transfer between LET and SiGDY is a precondition for the adsorption of the LET molecule with proper binding energies, which delivers the Si atoms with a significant positive charge.
