“…Wearables are tiny, lightweight devices containing a power source, sensors, a data processing and storage core, actuators, and a communication interface that are worn on the body or incorporated into everyday wear items such as clothes, footwear, or accessories. They represent the forefront of electronics, requiring maximum performance with minimum power outrage, in a tiny amount of space and even in harsh environments . In a review published in 2019, Krishnan et al summarized the progress in 2D and 3D graphene-based composites as emerging electrochemical as well as fluorescent flexible biosensing wearables for detecting a diverse variety of biomolecules with enhanced susceptibility, selectivity, and low detection limits.…”

The sensitivity and selectivity of a wearable biosensor toward a target biochemical analyte, as determined by the elimination of other interfering chemical species, are used to assess its performance.…”

Graphene, attributable to its exceptional electrical, chemical, physical, mechanical, thermal, structural, and optical characteristics, has evolved into a remarkable and revolutionary substance with which scientists are tinkering and molding its various forms. Currently, as greener resources are more approachable, for environmental and human health reasons, researchers are now employing diverse forms of natural resources, such as plant resources (flowers, wood, leaves, etc.), edibles (fruits, vegetables, cookies, chocolate, coffee, tea, etc.), biowaste, or any other kind of natural resources, by using different methods for their synthesis, such as the hydrothermal method, chemical vapor deposition, thermal exfoliation, freeze-drying, and so on, for framing different forms of graphene or its hybrids or even for the synthesis of graphene itself. In this review, we highlight several natural resources along with the biowaste materials to fabricate widely approachable graphenes which can also be transformed into different forms to make them more environmentally protected. We included here the safer synthetic processes, as well as many sectors where graphene and its various forms have intriguing potential. Future graphene research is anticipating new paths as the demand for the protection of the environment and sustainable alternatives is increasing.

“…In this context, it is vital to diagnose wound infection as early as possible in order to ensure the best treatment course for the patient. Currently used diagnostic methods are represented by clinical inspection and microbiological assays [ 4 , 5 , 6 ]. Despite being routinely used, these methods present several disadvantages such as inaccuracy, need for traumatic bandage removal and reliance on the physician’s expertise in the case of clinical examination.…”

“…The development of wearable devices is faced with numerous challenges in respect to the materials used, energy sources and data transmission [ 5 ]. The incorporated materials need to be biocompatible and tailored so that they can conform to the curvilinear surface of the skin [ 5 , 6 ]. Moreover, they need to be flexible and resistant in order to ensure the user’s free movement [ 7 ].…”

“…Moreover, they need to be flexible and resistant in order to ensure the user’s free movement [ 7 ]. Energy sources such as batteries are difficult to miniaturize and incorporate into wearable devices [ 6 ], but are indispensable for their operation and proper functioning, so it is necessary to find a solution to solve this inconvenience. Numerous challenges are also posed by designing appropriate and safe ways of wireless communication between the sensor and devices such as laptops and smartphones [ 5 , 7 ].…”

Wearable Sensors for the Detection of Biomarkers for Wound Infection

et al. 2021

Infection represents a major complication that can affect wound healing in any type of wound, especially in chronic ones. There are currently certain limitations to the methods that are used for establishing a clinical diagnosis of wound infection. Thus, new, rapid and easy-to-use strategies for wound infection diagnosis need to be developed. To this aim, wearable sensors for infection diagnosis have been recently developed. These sensors are incorporated into the wound dressings that are used to treat and protect the wound, and are able to detect certain biomarkers that can be correlated with the presence of wound infection. Among these biomarkers, the most commonly used ones are pH and uric acid, but a plethora of others (lactic acid, oxygenation, inflammatory mediators, bacteria metabolites or bacteria) have also been detected using wearable sensors. In this work, an overview of the main types of wearable sensors for wound infection detection will be provided. These sensors will be divided into electrochemical, colorimetric and fluorimetric sensors and the examples will be presented and discussed comparatively.
