“…In an example, Shukla et al has reported the evolution of the carbonyl group in chitin after grafting with polyaniline under optimum conditions. Thus, the obtained polymer-based composite matrix was reported suitable for sensing of cupric ion in trace level after monitoring the induced potential developed after interaction of cupric ion and chitin grafted polyaniline [ 56 ]. The explored potentiometric setup was shown in Fig.…”

Impact of macro molecular theory on the progress of sensing sciences and technology has been presented in the light of materials developments, advances in physical and chemical properties. The chronological advances in the properties of macromolecules have significantly improved the sensing performances towards gases, heavy metals, biomolecules, hydrocarbon, and energetic compounds in terms of unexplored sensing parameters, durability, and working lifetime. In this review article, efforts have been made to correlate the advances in structure and interactivity of macro-molecules with their sensing behavior and working performances. The significant findings on the macromolecules towards advancing the sensing sciences are highlighted with the suitable illustration and schemes to establish it as a potential “microanalytical technique” along with existing challenges.

“…Polyaniline (PANI) is a conductive polymer, and there are some stable oxidation forms of it: semi-oxidized emeraldine base (EB) which could convert into emeraldine salt (ES) through a portion, fully oxidized pernigraniline base (PNB) and fully reduced leucoemeraldine base (LEB) [89,[95][96][97][98][99][100]. Such a polymer could be employed for fabricating a responsive surface.…”

Diverse unique surfaces exist in nature, e.g. lotus leaf, rose petal and rice leaf. They show similar contact angles but different adhesion properties. According to the different wettability and adhesion characteristics, this review reclassifies different contact states of droplets on surfaces. Inspired by the biological surfaces, smart artificial surfaces have been developed which respond to external stimuli and consequently switch between different states. Responsive surfaces driven by various stimuli, e.g. stretching, magnetic, photo, electric, temperature, humidity and pH, are discussed. Studies reporting on either atmospheric or underwater environments are discussed. The application of tailoring surface wettability and adhesion includes microfluidics/droplet manipulation, liquid transport and harvesting, water energy harvesting and flexible smart devices. Particular attention is placed on the horizontal comparison of smart surfaces with the same stimuli. Finally, the current challenges and future prospects in this field are also identified.

“…Polymers from natural sources such as chitin [95], gelatin [106], and chitosan [11,72,160,177] layers were employed with simple steps for electrode modification. Despite the greenness of this alternative, the solubility of biopolymers in water is generally higher than artificial ones, which hinder the lifetime of the sensors.…”

An overview of Structured Biosensors for Metal Ions Determination

et al. 2021

View full text Add to dashboard Cite

The determination of metal ions is important for nutritional and toxicological assessment. Atomic spectrometric techniques are highly efficient for the determination of these species, but the high costs of acquisition and maintenance hinder the application of these techniques. Inexpensive alternatives for metallic element determination are based on dedicated biosensors. These devices mimic biological systems and convert biochemical processes into physical outputs and can be used for the sensitive and selective determination of chemical species such as cations. In this work, an overview of the proposed biosensors for metal ions determination was carried out considering the last 15 years of publications. Statistical data on the applications, response mechanisms, instrumentation designs, applications of nanomaterials, and multielement analysis are herein discussed.
