“…[114] While excellent compatibility of ILs with plenty of nanoparticles makes the ionogel nanocomposites show amazing potentials in the field of materials science. There has been a lot of ionogel nanocomposites developed, nanoparticles including SiO 2 , functionalized SiO 2 , halloysite nanotubes (HNTs), metal oxide (such Fe 3 O 4 ), carbon nanomaterials [115][116][117][118][119][120][121][122] and so on have been applied in ionogels to date. [123][124][125][126][127] It's worth noting that nanometal materials such as silver nanowires (AgNWs) or silver nanoparticles (AgNPs) have been serving as conductive filler in hydrogels for a long time.…”

Ionogels have aroused wide interests in the field of flexible electronics. The combination of solid‐state networks and ionic liquids opens up thousands of possibilities for ionogels. The unique structures of ionogels endow them excellent mechanical properties, conductivity and thermal stability to approach the challenge of flexible electronic. A large number of new ionogels have been developed by different methods including the exchange of solution, polymeric ionic liquid and in‐situ reactions in ionic liquids (gelation of low molecular weight gelators, self‐assembly of block polymers, formation of double‐network structure, ionogel nanocomposites and direct polymerization of polymerizable monomers). The aim of this review is to discuss different preparation methods of ionogels and the comparison of their advantages.

Highly fluorescent carbon dots from wheat bran as a novel drug delivery system for bacterial inhibition

et al. 2020

In this study, we prepared carbon dots (CDs) from wheat bran via hydrothermal treatment at 180°C for 3 h. The prepared CDs showed blue‐green fluorescence under UV light. The fluorescence emission study of the CDs revealed that they showed maximum fluorescence emission at 500 nm. The prepared CDs showed a high quantum yield of 33.23%. Solvent‐dependent fluorescence emission analysis of the CDs was performed to study the variation in fluorescence emission characteristics with solvent polarity. The prepared CDs were conjugated with amoxicillin (AMX) to explore its potential for use as a drug delivery agent for AMX. The drug release profile of the CD–AMX conjugates was analyzed at different pH (5.0, 6.8 and 7.2) to study drug release kinetics. CD–AMX conjugates showed notable bacterial inhibition against Gram‐positive (S. aureus) and Gram‐negative (E. coli) strains with minimal cytotoxic effects, indicating its potential as a promising antibacterial drug delivery system.

The nanocomposites (NCs) of cross-linked polyaniline (CPA) with a variety of carbon nanomaterials (CNMs) (CPA/CNMs NCs) was prepared by the chemical oxidative copolymerization of PANI and p-phenylenediamine (PPDA) with triphenylamine (TPA) in the presence of CNMs. The results of XRD, FTIR and Raman indicated that the CPA/CNMs NCs were effectively synthesized with strong interactions among the constituents. The morphology study demonstrated that CNMs were well coated by CPA and produce a well-aligned nanorod core-shell structure with the large surface area which may be more beneficial to electrical conductivity when used as electrode materials. Differential thermal analysis techniques (TGA-DTG) were used to characterize the thermal stability of NCs. The heat of formation of CPA monomer from TPA, PPDA and aniline (ANI) were computed using Density Functional Theory (DFT) calculations. The NCs of G-MWCNTs demonstrate higher affinity to oxidation of Chlorophenols (CPHs) than glassy carbon electrode (GCE), CPA/GCE and the other NCs. Differential pulse voltammetry (DPV) was used for the trace determination of 2,4-dichlorophenol (2,4-DCP). Under the optimum conditions, the peak current of 2,4-DCP was proportional to its concentration in the range of 0.05-0.6 μmol/L. The detection limit was 7.6 nmol/L. The method was successfully applied for the determination of 2,4-DCP in fish farm water with satisfactory recoveries. The suggested method has an advantage to be used for water samples due to its short analytical time, rapid response, high sensitivity, and excellent selectivity with good reproducibility.
