The rapid population growth, increasing global energy demand, climate change, and excessive use of fossil fuels have adversely affected environmental management and sustainability. Furthermore, the requirements for a safer ecology and environment have necessitated the use of renewable materials, thereby solving the problem of sustainability of resources. In this perspective, lignocellulosic biomass is an attractive natural resource because of its abundance, renewability, recyclability, and low cost. The ever-increasing developments in nanotechnology have opened up new vistas in sensor fabrication such as biosensor design for electronics, communication, automobile, optical products, packaging, textile, biomedical, and tissue engineering. Due to their outstanding properties such as biodegradability, biocompatibility, non-toxicity, improved electrical and thermal conductivity, high physical and mechanical properties, high surface area and catalytic activity, lignocellulosic bionanomaterials including nanocellulose and nanolignin emerge as very promising raw materials to be used in the development of high-impact biosensors. In this article, the use of lignocellulosic bionanomaterials in biosensor applications is reviewed and major challenges and opportunities are identified.

“…Nanocellulose (NC) is a nanostructured compound , resulting from the cellulose reworking, with cellulose being one of the most abundant natural resources easy to isolate from wood, fibers, and various byproducts and waste from important industries (e.g., food processing industry, agriculture, and packaging). Due to its outstanding properties such as high specific surface area and superior mechanical properties, NC was employed in many studies conducted toward the development of green or sustainable nanocomposite materials.…”

Sustainable nanocomposite materials based on different functionalized nanocellulose (NC) structures embedded in epoxidized linseed oil (ELO) were developed as foundation toward a greener approach for anticorrosive coating evolution. The work leans on functionalization with (3-aminopropyl) triethoxysilane (APTS), (3-glycidyloxypropyl)trimethoxysilane (GPTS), and vanillin (V) of NC structures isolated from plum seed shells, evaluated as potential reinforcing agents for the increase of thermomechanical properties and water resistance of epoxy nanocomposites from renewable resources. The successful surface modification was confirmed from the deconvolution of X-ray photoelectron spectra for C 1s and correlated with Fourier transform infrared (FTIR) data. The secondary peaks assigned to C−O−Si at 285.9 eV and C−N at 286 eV were observed with the decrease of the C/O atomic ratio. Compatibility and efficient interface formation between the functionalized NC and the biobased epoxy network from linseed oil were translated as decreased values for the surface energy of bio-nanocomposites and better dispersion imaged through scanning electron microscopy (SEM). Thus, the storage modulus of the ELO network reinforced with only 1% APTS-functionalized NC structures reached 5 GPa, an almost 20% increase compared with that of the neat matrix. Mechanical tests were applied to assess an increase of 116% in compressive strength for the addition of 5 wt % NCA to the bioepoxy matrix.

“…Recently, there have been reports regarding nanocellulose as the sensor material including gas sensor, chemical sensors, biosensor, heavy metal ion sensing, temperature sensor and strain sensor [ 48 , 49 , 50 , 51 , 52 ]. Since the nanocellulose has a large surface area [ 53 ] and is rich with the hydroxyl group [ 54 ], it can be functionalized with other chemicals depending on the targeted analytes.…”

Chemical sensors are a rapidly developing technology that has received much attention in diverse industries such as military, medicine, environmental surveillance, automotive power and mobility, food manufacturing, infrastructure construction, product packaging and many more. The mass production of low-cost devices and components for use as chemical sensors is a major driving force for improvements in each of these industries. Recently, studies have found that using renewable and eco-friendly materials would be advantageous for both manufacturers and consumers. Thus, nanotechnology has led to the investigation of nanocellulose, an emerging and desirable bio-material for use as a chemical sensor. The inherent properties of nanocellulose, its high tensile strength, large specific surface area and good porous structure have many advantages in its use as a composite material for chemical sensors, intended to decrease response time by minimizing barriers to mass transport between an analyte and the immobilized indicator in the sensor. Besides which, the piezoelectric effect from aligned fibers in nanocellulose composites is beneficial for application in chemical sensors. Therefore, this review presents a discussion on recent progress and achievements made in the area of nanocellulose composites for chemical sensing applications. Important aspects regarding the preparation of nanocellulose composites using different functionalization with other compounds are also critically discussed in this review.
