Cellulose-based sensors for metal ions detection

Cellulose-based fluorescent macromolecular sensors and their ability in 2, 4, 6-trinitrophenol detection

“…Cellulose is considered to be the main raw material of the world's energy and chemical industry due to its abundant sources, non-toxic, non-polluting, easy to modify, and good biocompatibility (Fan et al 2020;Huang et al 2020). As a polyhydroxyl linear polymer, cellulose could undergo typical etheri cation (You et al 2013), esteri cation (Kusuma et al 2019), oxidation (Imamura et al 2020) and other reactions (Fuchs and Zhang 2019).…”

A Review of Cellulose Coarse-Grained Models and Their Applications

“…CNCs have high aspect ratio and excellent mechanical properties. Therefore, CNCs were utilized for many applications in various fields ranging from medicine [10] to environmental science [11,12] and energy storage [13], to name a few. However, one particular characteristic of cellulose can be even as important as its excellent mechanical properties and this is that cellulose is a biobased, and thus biodegradable material.…”

Recent advances in cellulose-based membranes for their sensing applications

“…Sensors are widely used in various areas of social development and human life, such as industrial production, agricultural planting, environmental detection and disease diagnosis (Ghoneim et al 2019 ). According to the changes of environmental factors, sensors can be divided into three categories: physical sensors that respond to pressure/strain, temperature and humidity; chemical sensors that respond to metal cations, non-metal ions, pH, gas/vapor and toxic organic compounds; and biosensors that respond to biomolecules and pathogens (Dai et al 2020 ; Zhang et al 2020 ; Fan et al 2020a , b ). At present, although the traditional instrument analysis methods have the merits of sensitivity and professionalism, they still exhibit some drawbacks: expensive instruments, complicated operation steps and professional operators.…”
