Summary: Cellulose is an abundant organic substance with various applications such as paperboard production, drug delivery, and food packaging due to its bio-renewable and bio-degradable properties. Radical polymerization is commonly used to create cellulose derivatives with improved properties, by reacting cellulose with small organic fragments like methacrylate and styrene. Initiators like Fenton's reagent and controlled radical polymerization methods are utilized to generate free radicals on the cellulose backbone for grafting purposes, allowing for the development of functional cellulose with enhanced physical and chemical properties.

Summary: A staged-thermal-initiation RAFT polymerization method is reported for the synthesis of polymers with high thiol end-group fidelity, which show high efficiencies for grafting to various gold nanoparticles (GNPs). Experimental proof shows that the decrease of end-group fidelity with molecular weight is caused by the gradual decomposition of the initiator. The positive correlation between end-group fidelity of polymers and grafting-to efficiency is illustrated through grafting-to assays for various GNPs.

Summary: This research demonstrates the controlled synthesis of graft and branched copolymers without intermediate purification using one-pot or one-pass processes. The formation of poly(methacrylate) copolymers with pendent reversible addition-fragmentation chain transfer (RAFT) agent functionalities was performed through selective photoactivation, followed by a nonselective photoinduced chain extension to provide tailored graft copolymers. By alternating the light sources, a range of macromolecular architectures could be prepared from the same starting materials, showing the versatility and flexibility of this approach.

Summary: A hybrid nanocomposite of N,S-doped carbon dots/carbon nanotube-poly(amidoamine) dendrimer was synthesized and used as a highly selective electrochemical sensor for the determination of imatinib mesylate. The nanocomposite showed excellent electrocatalytic properties, generating a higher oxidation peak current for imatinib mesylate compared to other electrodes. The N,S-CDs/CNTD/GCE exhibited a linear relationship between concentration and oxidation peak current of imatinib mesylate, with a detection limit of 3 nM. The reproducibility and stability of the sensor were also excellent when quantifying imatinib mesylate in blood-serum samples.

Summary: The development of dynamic anticounterfeiting inks with time-dependent photochromism and photoluminescence characteristics has gained significant interest in advanced encryption systems. These inks have various applications, such as tracking UV rays and gas leakage, as well as quality monitoring. In this study, colloidal nanoparticles were synthesized using semi-continuous copolymerization and then incorporated with a photochromic compound to prepare the dynamic inks. The optical properties of the inks depended on the chain polarity and flexibility of the nanoparticles, and their time-dependent features were attributed to the gradual transformation of the photochromic compound under visible light induction. These innovative inks have achieved unprecedented advances in the field of information security and encryption.

Summary: Smart polymers with different responses to induced stimuli have attracted much attention. Polymers with fluorescent properties have potential applications in fluorescence chemosensors, optoelectronics, molecular thermometers, organic light-emitting diodes, molecular imaging, storage data security, drug delivery carriers, and encryption. Fluorescence resonance energy transfer (FRET) is an advanced optical mechanism that can be controlled by the swelling, aggregation, or collapsing of smart polymers, thereby affecting the spatial distance and efficiency. This review article focuses on the application of FRET in smart polymers for imaging and detection, based on the modulation of FRET efficiency by the smart polymer response to various stimuli including temperature, pH, light, solvent, glucose, and mechanical force.
