“…As shown in Figure 3, by increasing hole radius in same volume, the surface-to-volume ratio increases and the greater the surface-to-volume ratio, the higher will be the light penetration into the structure, and the larger will be the number of free electrons that start to oscillate. Consequently, the heat power increases along with the redshift (Asgharian et al , 2020). These are the reasons we have used the porous nanocubes in our structure.…”

Purpose The purpose of this study is to design a plasmonic structure that can be used simultaneously as a heater and a refractive index sensor applicable for heating and sensing cycles of lab-on-chip (LOC). Design/methodology/approach The authors report on the full optical method applicable in the heating and sensing cycles of LOC based on the plasmonic nanostructure. The novelty of this proposed structure is due to the fact that a structure simultaneously acts as a heater and a sensor. Findings In terms of the performance of the proposed structure as an analyte detection sensor, in addition to the real-time measurement, there is no need to labeling the sample. In terms of the performance of the proposed structure as a plasmonic heater, the uniformity and speed of the heating and cooling cycles have been greatly improved. Also, there is no need for experts and laboratory conditions; therefore, our proposed method can meet the conditions of point of care testing. Originality/value The authors confirm that this work is original and has not been published elsewhere nor it is currently under consideration for publication elsewhere.

“…The optical and thermal behavior of nanoparticles is determined by several factors, including their shape, size, [15,16] material [17,18], environment, [19] arrangement and interaction. [20,21] When nanoparticles are excited by sunlight, the Sun's spectrum must match the absorption spectrum of the nanoparticles.…”

Metal nanoparticles (NPs) with subwavelength dimensions exhibit plasmonic phenomena in resonance frequency and can absorb a portion of light non-radiatively and thermally. This property of NPs can be used in various applications such as seawater desalination, where the thermal power generated by them can be utilized. In this paper, we have designed and analyzed NPs to achieve maximum absorption and heat generation under solar irradiance. The NPs were arranged on a glass substrate in the most optimal pattern to obtain the highest possible absorption and heat generation. We utilized a numerical method to determine the total absorbed power of the NPs under solar irradiance. The shape, material, size and arrangement and interaction of the NPs determine their optical behavior, and, as a result, their thermal behavior. Therefore, we designed cylindrical, cubic, triangular, and hexagram-shaped NPs with the same volume of metal, choosing the material from noble metals such as Ag, Au, Cu, and Al. In the first step, we calculated the absorption cross-section of NPs using the Finite Difference Time Domain (FDTD) method. We then multiplied the solar irradiance intensity by the cross-section obtained in the first step. In the final step, we integrated the graph obtained in the solar spectrum to obtain the total absorbed power of the NPs. To determine the best arrangement period of the NPs, we utilized the Particle Swarm Optimization (PSO) method. This algorithm helped us find the period with the highest absorbed power. Aluminum hexagram nanoparticles, having the highest absorbed power and cost-effectiveness in manufacturing, were considered as the main candidates for the structure.
