“…Meanwhile, we observed a good linear relationship between I/I 0 and the Hg 2+ concentration ranging from 0 to 75 μM, and as low as 0.01 μM Hg 2+ could be detected. Therefore, the lowest detectable concentration of CQDs for Hg 2+ was 10 nM, which is comparable with these reported values ( Table S1 ) 9 14 34 35 36 37 .…”

A facile, simple and low-cost approach for synthesizing highly fluorescent carbon quantum dots (CQDs) from thermal treatment of sustainable hair has been developed. The resultant CQDs exhibited strong blue emission with a quantum yield of 10.75%, excellent photostability and high stability in high salt conditions. As the fluorescence of CQDs can be efficiently quenched by Hg2+, the CQDs can be constructed as a nanosensor for Hg2+ with good sensitivity and selectivity. And as low as 10 nM Hg2+ can be successfully detected.

“…The optical properties of carbon quantum dots are intriguing because different studies often produce contradictory results. For instance, carbon quantum dots have been synthesized from microcrystalline cellulose using an ionic liquid, 1buty-3-methylimidazolium chloride, as a catalyst 256 . These carbon quantum dots exhibited excitation-dependent fluorescence emission behavior.…”

With increasing environmental and ecological concerns due to the use of petroleum based chemicals and products, the synthesis of fine chemicals and functional materials from natural resources is of great public value. Nanocellulose may prove to be one of the most promising green materials of modern times due to its intrinsic properties, renewability and abundance. In this review, we present nanocellulose-based materials from sourcing, synthesis, and surface modification of nanocellulose, to materials formation and applications. Nanocellulose can be sourced from biomass, plants or bacteria, relying of fairly simple, scalable and efficient isolation techniques. Mechanical, chemical, enzymatic treatments, or a combination of these, can be used to extract nanocellulose from natural sources. The properties of nanocellulose are dependent on the source, the isolation technique and potential subsequent surface transformations. Nanocellulose surface modification techniques are typically used to introduce either charged or hydrophobic moieties, and include: amidation, esterification, etherification, silylation, polymerization, urethanization, sulfonationand phosphorylation. Nanocellulose has excellent strength, Young's modulus, biocompatibility, and tunable self-assembly, thixotropic and photonic properties, which are essential for the applications of this material. Nanocellulose participates in the fabrication of a large range of nanomaterials and nanocomposites, including those based on polymers, metals, metal oxides and carbon. In particular, nanocellulose complements organic-based materials, where it imparts its mechanical properties to the composite. Nanocellulose is a promising material whenever material strength, flexibility and/or specific nanostructuring are required. Applications include functional paper, optoelectronics and antibacterial coatings, packaging, mechanically reinforced polymer composites, tissue scaffolds, drug delivery, biosensors, energy storage, catalysis, environmental remediation and 3 electrochemical controlled separation. Phosphorylated nanocellulose is a particularly interesting material, spanning a surprising set of applications in various dimensions including bone scaffolds, adsorbents, flame retardants and as a support for the heterogenization of homogeneous catalysts.

“…Biological Materials for the Matrix—Starch and Cellulose : Photoluminescence films based on a blend of starch and/or cellulose as matrix and emitting compounds are an emerging concept in white hybrid ILEDs since 2014 . They have also been applied to H 2 production under visible light, sensing, membrane separation, biosensing, and ion detection, among others . Similar to the coatings with BSM matrix, both materials are relatively low‐cost and form porous films with a high thermal stability, high compatibility with artificial and biological compounds, high transmittance and a refractive index of 1.5.…”

Solid-state lighting (SSL) is one of the biggest achievements of the 20 th century. It has completely changed our modern life with respect to general illumination (light-emitting diodes), flat devices and displays (organic lightemitting diodes), and small labeling systems (light-emitting electrochemical cells). Nowadays, it is however mandatory to make a transition toward green, sustainable, and equally performing lighting systems. In this regard, several groups have realized that the actual SSL technologies can easily and efficiently be improved by getting inspiration from how natural systems that manipulate light have been optimized over millennia. In addition, various natural and biocompatible materials with suitable properties for lighting applications have been used to replace expensive and unsustainable components of current lighting devices. Finally, SSL has also started to revolutionize the biomedical field with the achievement of efficient implantable lighting systems. Herein, the-state-of-art of (i) biological materials for lighting devices, (ii) bioinspired concepts for device designs, and (iii) implantable SSL technologies is summarized, highlighting the perspectives of these emerging fields.
