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.

“…Another example of Cu 2+ detection is a label-free biosensor based on a graphene field-effect transistor described by Wang et al [ 87 ]. The working principle takes advantage of the change in surface charge (and thus the potential of the gate modified with aptamer sequence 5′ -HS-S-(CH 2 ) 6 - ATC GCG ATA TTT TCT GTA GCG ATT CTT GTT TGA GCG CTC GGT ACG AAC AGA -3′) due to a change in its conformation upon copper ions binding.…”

Recently nucleic acids gained considerable attention as selective receptors of metal ions. This is because of the possibility of adjusting their sequences in new aptamers selection, as well as the convenience of elaborating new detection mechanisms. Such a flexibility allows for easy utilization of newly emerging nanomaterials for the development of detection devices. This, in turn, can significantly increase, e.g., analytical signal intensity, both optical and electrochemical, and the same can allow for obtaining exceptionally low detection limits and fast biosensor responses. All these properties, together with low power consumption, make nucleic acids biosensors perfect candidates as detection elements of fully automatic portable microfluidic devices. This review provides current progress in nucleic acids application in monitoring environmentally and clinically important metal ions in the electrochemical or optical manner. In addition, several examples of such biosensor applications in portable microfluidic devices are shown.

“…22 Moreover, several studies using A-GFETs for ion detection have also been reported, with the transistors exhibiting high specicity, fast response, and low limit of detection compared with traditional detection methods. [23][24][25] The A-GFET sensor can be fabricated on a tiny silicon chip (2 × 2 cm); thereby promoting the development of miniaturization and portability of the ion-detection equipment. Nevertheless, some problems remain to be solved when the A-GFET is applied for the detection of metal ions in oily wastewater.…”
