“…As a result, we can now effectively manage electromagnetic wave properties, including intensity, phase, and polarization, at both subwavelength and wavelength levels [32][33][34]. Metasurfaces have been successfully employed for various exotic applications, including structured beam generation [35][36][37], meta-holography [38][39][40][41], biomedical imaging [42][43][44], lensing system structured beam generation [45][46][47], perfect vortex beams [48][49][50], intelligent and multi-function surfaces [51][52][53], and efficient energy harvesting [54][55][56][57]. Metasurfaces have the potential to revolutionize optical microscopy techniques, particularly blood cancer diagnosis.…”

Blood cancer remains a major global health challenge, emphasizing the critical need of early diagnosis, for effective treatment and improved patient outcomes. Recently, quantitative phase imaging (QPI) based study of cancerous cell morphology, viability and proliferation, attracts the attention of the pathologist and researchers. In this research article, we have introduced customized QPI based imaging tool for investigation of malignant blood cells for the early detection of cancer. The proposed tool enables the measurement of optical path length variations which gives the provision of labelfree, high-resolution imaging of blood cells, allowing for the precise quantification of cellular parameters such as volume, thickness, and dry mass. The proposed low-cost configuration referred as self-referencing QPI system, makes use of the laser beam for generation of the interferograms. Moreover, this technique has the advantage of numerical focusing, and it is not necessary to place the imaging device at the image plane of the magnifying lens. Therefore, efficient autofocusing feature is designed that ensures the efficacious detection, omitting human error and declining the time-consumption. Moreover, the precision of early cancer diagnosis is enhanced through the integration of convolutional neural network (CNN) and QPI technique, which reduces the likelihood of inaccurate imaging. The non-invasive nature of proposed imaging system minimizes patient discomfort and enables real-time monitoring of disease progression. The methodology demonstrates promising results in the early detection of blood cancer and impassive the need of stained sample preparation. This research contributes to the advancement of personalized medicine and underscores the importance of leveraging quantitative phase imaging for early intervention and improved management of blood cancer.

“…Therefore, the use of nanoparticles in sports apparel is a promising area of research, with the potential to improve athletes' performance and reduce the risk of injury. However, there are still some difficulties that need to be overcome for this technology to become widely used, such as costs, as nanoparticles are generally more expensive than conventional materials and safety, nanoparticles can be toxic if not properly used and it is necessary to see the influence on performance (Zhang et al, 2023).…”

The present study aims to carry out a lifting, analysis, and description of scientific publications such as articles on nanoparticles in sportswear with the focus on heat control, odor, electricity generation and bacterial infections. Thus, an exploratory search was realized in the ScienceDirect and Scopus from 2019 to Sep 2023. In relation to the production of nanoparticles and fabric, the nanocoating technique is used and can be applied directly to the fabric fiber or with application in the form of a spray on the item of clothing. The application/ combination of nanomaterials such as titanium dioxide (TiO 2 -NPs), silver nanoparticles (Ag-NPs), zinc oxide nanoparticles (ZnO-NPs), and polymer fibers (cellulose diacetate, bacterial cellulose, and polytetrafluoroethylene) allow properties such as antibacterial activity, solar protection and superhydrophobicity to provide breathability, aesthetics, flexibility, and the ability to not cause allergic reactions compared to cotton fabric generally relating the main mechanism to the generation of free radicals and high electronic conductivity.

“…[4] With the incorporation of electronic components, metasurfaces have been made programmable to enable adapting their properties with regard to considered practical applications. [5][6][7] However, human operation, necessary for each reconfiguration, has been a major drawback for a long time. Recently, self-adaptive metasurfaces and reconfigurable intelligent surfaces (RIS) have been proposed.…”

In the face of the challenges posed by the advent of 5G, Internet of Things (IoT) and requirements of future communication generations, the urgent need for cutting‐edge technologies capable of adapting their operation to a variety of dynamic tasks for efficient signal propagation management is clear. Connected intelligent metasurfaces, distinguished by their ability to dynamically and autonomously adapt their responses, and able to interact with an external uncontrollable and fast‐changing communication environment to benefit from collective intelligence so as to determine the required action, are emerging as an innovative solution in this field. Herein, an intelligent connected system based on a programmable metasurface reflector, is presented and assessed in two scenarios simulating dynamic uplink and downlink communications. For the uplink configuration, the metasurface is exploited for the estimation of the direction of arrival (DOA) of an incoming wave, while for the downlink scenario, it enables the automated tracking of mobile targets using global positioning system (GPS) data updated from a real‐time database. Experimental results highlight the responsiveness of the metasurface and demonstrate efficiency in wave focusing and mobile target tracking.
