“…[26][27][28] Optical sensors has been steadily developed since the first laser has introduced in 1960. 29 However, it has been difficult to attract attention on the optical sensors in terms of ecosystem monitoring since the sensitivity and selectivity of the optical sensors ware not sufficient to be used for ecosystem compared to electrical and electrochemical sensors. The nanotechnology has made it possible to improve the sensing performance of the optical sensor with a high sensitivity and selectivity.…”

Rapid industrial growth has severely impacted ecosystems and aggravated economic and health risks to society. Monitoring of ecosystems is fundamental to our understanding of how ecosystem change impacts resources and is critical for developing data-based sustainability. Thus, the design and development of optimized sensors for ecosystem monitoring have received increasing attention.This review provides a comprehensive overview of systematic sensor design strategies for ecosystem monitoring from the material level to the form factor level. We discuss the fundamental transducing mechanisms of a representative sensor system including optical, electrical, and electrochemical sensors. We then review the sensor interfacing strategy for achieving stable and real-time monitoring of environmental biochemical factors from air, water, soil, and living organisms. Finally, we provide a summary of the current performance and prospects of this state-of-the-art sensor technology and an outlook on opportunities for possible future research directions in this emerging field.

“…Optical sensors are defined as the light‐based sensors in which the change in signal or result can be observed easily where the signal transducer can be colorimetric, fluorescence, luminescence, or interferometric (Mönch & Zappe, 2008; Shahdeo & Gandhi, 2022). Optical sensors have emerged as one of the most reliable platforms for medical diagnosis due to their simple, rapid and cost‐effective nature (Tjandra et al, 2020). In this section, we have reviewed globally developed optical sensors for the detection of clinical biomarkers for CKD.…”

Chronic kidney disease (CKD) is emerging as one of the major causes of the increase in mortality rate and is expected to become 5th major cause by 2050. Many studies have shown that it is majorly related to various risk factors, and thus becoming one of the major health issues around the globe. Early detection of renal disease lowers the overall burden of disease by preventing individuals from developing kidney impairment. Therefore, diagnosis and prevention of CKD are becoming the major challenges, and in this situation, biosensors have emerged as one of the best possible solutions. Biosensors are becoming one of the preferred choices for various diseases diagnosis as they provide simpler, cost‐effective and precise methods for onsite detection. In this review, we have tried to discuss the globally developed biosensors for the detection of CKD, focusing on their design, pattern, and applicability in real samples. Two major classifications of biosensors based on transduction systems, that is, optical and electrochemical, for kidney disease have been discussed in detail. Also, the major focus is given to clinical biomarkers such as albumin, creatinine, and others related to kidney dysfunction. Furthermore, the globally developed sensors for the detection of CKD are discussed in tabulated form comparing their analytical performance, response time, specificity as well as performance in biological fluids.

“…Sin embargo, los quimiosensores fluorescentes son los más abundantes y destacables dentro de esta clasificación ya que estos han sido ampliamente utilizados en diversos campos como la biología, fisiología, farmacología y ciencias ambientales (Wu et al, 2017;Díaz-Álvarez y Martin-Esteban, 2021;Al-Saidi y Khan, 2022;Krämer et al, 2022). Como ejemplos de la versatilidad que poseen este tipo de quimiosensores están los sensores bioquímicos que utilizan bioreceptores etiquetados con un fluoróforo, dichos bioreceptores pueden ser enzimas, sustratos, anticuerpos, entre otros y se utilizan para detectar biomoléculas específicas (Tjandra et al, 2020). De igual manera, dentro de esta clasificación se encuentran los sensores basados en nanopartículas tales como nano varillas de oro, plasmón de superficie mejorada por fluorescencia y puntos cuánticos, los cuales, son una clase emergente de sensores que utilizan las propiedades únicas de las nanopartículas para detectar una variedad de analitos biológicos.…”

La química supramolecular tiene como uno de sus objetos de estudio el reconocimiento molecular, el cual es un proceso que involucra cierta complementariedad y selectividad por parte de las especies que interactúan entre sí para generar el complejo o supramolécula, este proceso de reconocimiento específico de una molécula hacia otro se ha expandido y aplicado al diseño de sistemas que funcionen como sensores moleculares de diferentes especies ya sea de interés biológico o industrial. El objetivo del presente artículo es presentar el crecimiento y los principales logros que ha tenido este campo de la ciencia y tecnología mediante la revisión de conceptos clásicos en la química supramolecular y la presentación de ejemplos que muestran los principales resultados en cuanto al incremento y el avance en el desarrollo de sensores moleculares disponibles en la actualidad.
