“…Our results showed that oxygen-containing functional groups (e.g., epoxy groups) were the dominant sites of attack during biodegradation. GO degradation is positively correlated with the content of oxygen/oxygen-containing functional groups on the GO surface. , It is noted that oxygen content in the 14 C-labeled GO was only 4.6%, much lower than the GO film or GO powder in other biodegradation studies (from 28.9–44.7%). , In addition to direct unintentional release into the environment, GO-related materials have great application potential in agriculture, such as nanopesticides, nanofertilizers, and agricultural film coatings. , The degradation of these materials by insects could largely alter their fate and processes in agroecosystems.…”

“…Additionally, the assimilation of polystyrene plastics by yellow mealworms was reported to be 0.5% . Graphene materials are widely used as additives during plastic production (e.g., food packaging and agricultural films), , and yellow mealworms are widely recognized as beneficial insect species to decompose plastics. Therefore, graphene materials and plastics could be treated together through this newly revealed insect-based degradation route.…”

“…In addition to a crucial trophic level in natural ecosystems, insects also act as an important source of protein and fatty acids in aquaculture and stockbreeding. GO and other graphene materials are good carriers of nanofertilizers and nanopesticides, additives in agricultural films, and key materials of soil moisture sensors. ,, Insects could highly affect the fate of these GO materials in ecosystems. However, there is no report on the potential degradation of GO (or other nanomaterials) by insects to our knowledge.…”

Biodegradation of graphene materials is critical for understanding their environmental process and fate. Thus, biodegradation and mineralization of graphene oxide (GO) by an insect (yellow mealworms, Tenebrio molitor larvae) were investigated. Twenty mealworms could eat up a piece of GO film (1.5 × 1.5 cm) in 15 days. The ingested GO film underwent degradation, and the residual GO sheets were observed in the frass. Raman imaging confirmed that the residual GO (I D /I G , 1.16) was more defective than the pristine GO film (I D /I G , 0.95). 14 C analysis showed that GO sheets were partially mineralized into CO 2 (0.26%) and assimilated into biomass compositions (e.g., lipid and protein) (0.36%). Gut microbes and extracellular enzymes in yellow mealworms played crucial roles in GO degradation, and the predominant gut microbes for GO biodegradation were identified as Enterobacteriaceae bacteria (e.g., Escherichia−Shigella sp.). Two biodegradation products belonging to hydroxylated or carboxylated aromatic compounds were formed with the assistance of electrons and hydroxyl radicals in mealworm guts. These findings are useful for better understanding the environmental and biological fate of graphene materials.

“…Similar, 3D assemblies with carbon and attapulgite were shown to control the release of pheromone and nutrient loss. 9,31,32 Interestingly, after the 50th day, in the coated samples, there is an enhanced release; this could be because in this 50 days of incubation time, swelling of the egg white due to its oxygen absorption property or a slow lignin washing from JF may have caused more relaxation. 18 This may have paved the path for rapid release; similar cycles of slow and rapid release has also been reported in other bio-derived polymer based urea coatings.…”

A sustainable fertilizer coating using silica for urea release control has been developed using egg white as the binder, which forms an irreversible hydrophobic β-sheet on gentle heating and substitutes earlier petrochemical coatings. When the silica content is increased for diffusion control, the membrane becomes brittle; hence, for the first time here, jute grafted silica nanoring has been used, where the nanojute acts as a strong buckle for the egg white β-sheet fastener and serve as the sack for holding urea. Silica and egg white are inert, while the jute acts as an auto rate-cutter for spill-way pores in silica, which allows a threshold amount of nutrients to pass on initial wetting and then controls nutrient loss by swelling. Thus, both forms of loss, viz. volatility and liquid with humidity and flooding, respectively, get controlled. This eco-friendly noncovalent stable scalable urea coating shows 15% more efficiency in rice production.

Nanocarbons are emerging at the forefront of nanoscience, with diverse carbon nanoforms emerging over the last two decades. Early cancer diagnosis and therapy, driven by advanced chemistry techniques, play a pivotal role in mitigating mortality rates associated with cancer. Nanocarbons, with an attractive combination of well‐defined architectures, biocompatibility, and nanoscale dimension, offer an incredibly versatile platform for cancer imaging and therapy. This paper aims to review the underlying principles regarding the controllable synthesis, fluorescence origins, cellular toxicity, and surface functionalization routes of several classes of nanocarbons: carbon nanodots, nanodiamonds, carbon nanoonions, and carbon nanohorns. This review also highlights recent breakthroughs regarding the green synthesis of different nanocarbons from renewable sources. It also presents a comprehensive and unified overview of the latest cancer‐related applications of nanocarbons and how they could be designed to interface with biological systems and work as cancer diagnostics and therapeutic tools. The commercial status for large‐scale manufacturing of nanocarbons is also presented. Finally, it proposes future research opportunities aimed at engendering modifiable and high‐performance nanocarbons for emerging applications across medical industries. This work is envisioned as a cornerstone to guide interdisciplinary teams in crafting fluorescent nanocarbons with tailored attributes that can revolutionize cancer diagnostics and therapy.This article is protected by copyright.
