“…In this configuration, cellulose suffers modification through the cyclohexane ring in the presence of cerium ammonium nitrate, and aldehyde functional molecules such as RC attaches to cellulose -GMA -TEPA by imine reaction in DMF medium. 110 Linker's fragments may also be attached to the biomolecule, configuring a new way to form a cellulose bioconjugated system (Fig. 4(a2)).…”

“…One efficient strategy to break this bottleneck is to construct a dual‐mode visualization detection platform with two independent signals, such as the colorimetric‐fluorescent dual‐mode detection. [ 23 , 24 ] A series of studies proved that fluorophores, such as rhodamine‐based compounds, [ 25 ] 1,8‐naphthalimide derivatives, [ 26 ] cyanine derivatives, [ 27 ] and bodipy‐based derivatives, [ 28 ] can be used for it. In addition, nanoparticles modified with organic small‐molecule fluorescent probes, such as QDs, [ 29 ] metal‐based nanoparticles, [ 30 ] and MOFs, [ 31 ] have been introduced to construct the dual‐mode nanoprobes.…”

The design and development of ultra‐accurate probe is of great significance to chemical sensing in complex practical scenarios. Here, a self‐accelerating naphthalimide‐based probe with fast response and high sensitivity toward hydrogen peroxide (H2O2) is designed. By coupling with the specially selected upconversion nanoparticles (UCNPs), an ultra‐accurate colorimetric‐fluorescent‐upconversion luminescence (UCL) tri‐mode platform is constructed. Owing to the promoted reaction process, this platform demonstrates rapid response (< 1 s), an ultra‐low detection limit (4.34 nM), and superb anti‐interferent ability even in presence of > 21 types of oxidants, explosives, metallic salts, daily compounds, colorful or fluorescent substances. In addition, the effectiveness of this design is further verified by a sponge‐based sensing chip loaded with the UCNPs/probe in recognizing trace H2O2 vapor from interferents with the three characteristic colors existing simultaneously. The proposed design of probe and tri‐mode visualization detection platform is expected to open up a brand‐new methodology for ultra‐accurate sensing.

“…Apart from this, the maximum adsorption capacity/Langmuir adsorption capacity for the reported adsorbent, FSNC (172.412 mg/g) was found to be higher than that reported for various similar adsorbents for the removal of Hg 2+ ions. Some of the examples include bovine serum albumin‐protected gold nanoclusters‐loaded cellulose nanocrystal–alginate hydrogel beads (26 mg/g), 42 Rhodamine‐functionalized cellulose (35 mg/g), 43 jute‐nanofiber (85.5 mg/g), 44 l‐Cysteine functionalized bagasse cellulose nanofibers (116.822 mg/g), 45 novel fluorescent NC‐hydrogel based on gold nanoclusters (95.7 mg/g), 46 and diaminoguanidine functionalized cellulose (73.50 mg/g) 47 . In addition to the appreciable adsorption performance, the material is dual‐functional with significant antimicrobial activity.…”

To develop a green nanomaterial for specialty applications, spherical nanocellulose (SNC) was functionalized to a semicarbazone‐Schiff base via a polymer analogous reaction. Firstly, SNC was synthesized from cellulose extracted from huge forest biomass, pine needles (PNs). The glucopyranose ring of SNC was oxidatively cleaved at C2–C3 to form SNC‐dialdehyde (SNC‐DA) by periodate oxidation. Both the aldehydic groups generated were reacted with semicarbazide to form a semicarbazone‐Schiff base, referred to as functional spherical nanocellulose (FSNC). All the materials synthesized were characterized by FTIR, FESEM, EDS, TEM, and XRD studies. The FSNC was evaluated as an adsorbent for Hg2+ ions. The adsorption adhered to pseudo‐second order kinetics and Langmuir adsorption isotherm having a maximum adsorption capacity/Lungmuir adsorption capacity of 172.412 mg/g at 60 min. The selectivity of FSNC for Hg2+ ions was confirmed from its appreciable removal (82%) from solution in tap water and 70% with other metal ions. FSNC exhibited bifunctional nature as it possesses antimicrobial activity against bacteria, that is, Gram (+) (Bacillus aereus) and Gram (−) (Escherichia coli and Salmonella typhi), and a fungus Byssochlamys fulva. FSNC showed good recyclability up to eight sorption–desorption cycles. Thus, we have valorized biomass into an eco‐friendly and low‐cost bifunctional material as an adsorbent for Hg2+ ions cum antimicrobial agent.Highlights Spherical nanocellulose (SNC) prepared via acidic hydrolysis from pine needles SNC functionalized to semicarbazone‐based bifunctional Schiff base The Schiff base is a rapid and efficient Hg2+ ions adsorbent The Schiff base has good antimicrobial activities against Gram (−) bacteria Biowaste‐based adsorbent has the potential to sustain the bio‐circular economy
