Multi-stimuli responsive amphiphilic diblock copolymers by a combination of ionic liquid-mediated cationic polymerization and recyclable alloy nanoparticle-mediated photoRDRP

Multi-Stimuli Responsive Sequence Defined Multi-Arm Star Diblock Copolymers for Controlled Drug Release

“…To study the encapsulation capacity of the (PNIPAM- b -PMAA) 4 -UMB diblock copolymer nanocarrier, coumarin 102 (C102), a hydrophobic dye encapsulation, was studied using UV–vis spectroscopy. Results of this study revealed that the characteristic C102 absorbance (at 395 nm) 30 , 31 gradually decreased with time as shown in Figure 3 a, leading to 42% encapsulation after 24 h incubation as shown in Figure 3 c. The intensity of the fluorescence emission spectrum of C102 ( Figure 3 b) decreases after encapsulation compared with that of neat C102 solution, suggesting successful encapsulation of C102. The absorption and fluorescence intensity of C102 decreased after encapsulation inside the core of the nanocarrier due to a decrease in the solution concentration of C102 after encapsulation in the core of the self-aggregated nanospheres of the (PNIPAM- b -PMAA) 4 -UMB copolymer.…”

Nonmetallic modified zero-valent iron for remediating halogenated organic compounds and heavy metals: A comprehensive review

“…Practical application necessitates investigating NM-ZVI's long-term repeatability and exploring methods to enhance its structural integrity and durability [ 123 ]. Research should focus on novel approaches such as composites incorporation to protect NM-ZVI from corrosion and degradation [ 124 , 125 ], understanding underlying corrosion and aging mechanisms, and devising strategies to mitigate these issues for sustained remediation effectiveness.…”

Ionic Liquids: New Forms of Active Pharmaceutical Ingredients with Unique, Tunable Properties

“…However, to date, cytotoxicity studies have mostly been conducted on inherently antibacterial ILs, containing imidazolium, piperazinium, guanidinium, morpholinium, pyrrolidinium, pyridinium, quinolinium, pyridazinium, phosphonium, etc. cations and often prepared for different uses, e.g., as solvents. − …”
