“…The crosslinking agent has several active groups and can be linked to cellulose via chemical reactions such as etherification, esterification, and free radical polymerization. Crosslinking agents that are often utilized include epichlorohydrin [102], dicarboxylic acid [103], diisocyanate [104], and diacrylate [105]. To create interpenetrating polymer networks, cellulose can be crosslinked with other polymers such as PVA [106], chitosan [107], sodium alginate [108], and others.…”

We conceptualize bioresource upgrade for sustainable energy, environment, and biomedicine with a focus on circular economy, sustainability, and carbon neutrality using high availability and low utilization biomass (HALUB). We acme energy-efficient technologies for sustainable energy and material recovery and applications. The technologies of thermochemical conversion (TC), biochemical conversion (BC), electrochemical conversion (EC), and photochemical conversion (PTC) are summarized for HALUB. Microalgal biomass could contribute to a biofuel HHV of 35.72 MJ Kg−1 and total benefit of 749 $/ton biomass via TC. Specific surface area of biochar reached 3000 m2 g−1 via pyrolytic carbonization of waste bean dregs. Lignocellulosic biomass can be effectively converted into bio-stimulants and biofertilizers via BC with a high conversion efficiency of more than 90%. Besides, lignocellulosic biomass can contribute to a current density of 672 mA m−2 via EC. Bioresource can be 100% selectively synthesized via electrocatalysis through EC and PTC. Machine learning, techno-economic analysis, and life cycle analysis are essential to various upgrading approaches of HALUB. Sustainable biomaterials, sustainable living materials and technologies for biomedical and multifunctional applications like nano-catalysis, microfluidic and micro/nanomotors beyond are also highlighted. New techniques and systems for the complete conversion and utilization of HALUB for new energy and materials are further discussed.

“…These prodrugs could be hydrolysed under high intercellular esterase concentration of tumor cells and intramolecular structure rearranged into benzoquinone structure, which is the activated form to induce tumor cells apoptosis. Similar as β-lapachone, fluorescein (Pang et al., 2017) also possesses phenol hydroxyl structure or benzoquinone structure, which is nonfluorescent or fluorescent, respectively. Fluorescein diacetate, which is fixed to the phenol structure by ester bond, has become the most commonly used probe for detecting esterase concentration in tumor cells (Nilewski et al., 2018).…”

Nanoparticles have been developed for tumor treatment due to the enhanced permeability and retention effects. However, lack of specific cancer cells selectivity results in low delivery efficiency and undesired side effects. In that case, the stimuli-responsive nanoparticles system designed for the specific structure and physicochemical properties of tumors have attracted more and more attention of researchers. Esterase-responsive nanoparticle system is widely used due to the overexpressed esterase in tumor cells. For a rational designed esterase-responsive nanoparticle, ester bonds and nanoparticle structures are the key characters. In this review, we overviewed the design of esterase-responsive nanoparticles, including ester bonds design and nano-structure design, and analyzed the fitness of each design for different application. In the end, the outlook of esterase-responsive nanoparticle is looking forward.

“…Ethyl cellulose (EC), an important cellulose derivative, has high plasticity, biocompatibility, and heat and light resistance [13][14][15][16]. Remarkably, EC possesses excellent film-forming performance like other cellulose derivatives [17][18][19][20]. However, the brittleness of EC films restricts their applications in many fields.…”

Ethyl cellulose (EC), an important biomass-based material, has excellent film-forming properties. Nevertheless, the high interchain hydrogen bond interaction leads to a high glass transition temperature of EC, which makes it too brittle to be used widely. The hydroxyl group on EC can form a supramolecular system in the form of a non-covalent bond with an effective plasticizer. In this study, an important vegetable-oil-based derivative named dimer fatty acid was used to prepare a novel special plasticizer for EC. Dimer-fatty-acid-based thioether polyol (DATP) was synthesized and used to modify ethyl cellulose films. The supramolecular composite films of DATP and ethyl cellulose were designed using the newly-formed van der Waals force. The thermal stability, morphology, hydrophilicity, and mechanical properties of the composite films were all tested. Pure EC is fragile, and the addition of DATP makes the ethyl cellulose films more flexible. The elongation at the break of EC supramolecular films increased and the tensile strength decreased with the increasing DATP content. The elongation at the break of EC/DATP (60/40) and EC/DATP (50/50) was up to 40.3% and 43.4%, respectively. Noticeably, the thermal initial degradation temperature of the film with 10% DATP is higher than that of pure EC, which may be attributed to the formation of a better supramolecular system in this composite film. The application of bio-based material (EC) is environmentally friendly, and the novel DATP can be used as a special and effective plasticizer to prepare flexible EC films, making it more widely used in energy, chemical industry, materials, agriculture, medicine, and other fields.
