“…Recently, Sharma et al developed a new synthetic strategy that uses benzenesulfonate as a good leaving group instead of bromide and enabled the development of OE 2 imC 3 C using a general low-cost reagent. [30] This might allow further application of ZILs in plant gene engineering. Another challenge is the strong electrostatic interactions between ILs (ILs and ZILs) and water.…”

Zwitterionic molecules, such as zwitterionic liquids (ZILs) and polypeptides (ZIPs), are attracting attention for application in new methods that can be used to loosen tight cell wall networks in a biocompatible manner. These novel methods can enhance the cell wall permeability of nanocarriers and increase their transfection efficiency into targeted subcellular organelles in plants. Herein, we provide an overview of the recent progress and future perspectives of such molecules that function as boosters for cell wall‐penetrating nanocarriers.

“…Harsh conditions including high temperature, acidic and alkaline conditions, etc. make cellulose significantly soluble in particular solvents [47] whereas ILs don't demand such higher conditions to an extent. The use of high temperature accelerates the dissolution and degradation leading to lesser yields for regenerated cellulose [29].…”

“…Harsh conditions including high temperature, acidic and alkaline conditions, etc. make cellulose signi cantly soluble in particular solvents (Sharma et al 2021) whereas ILs don't demand such higher conditions to an extent. The use of high temperature accelerates the dissolution and degradation leading to lesser yields for regenerated cellulose (Usmani et al 2020) This kind of IL treatment has further advantages such as the pretreatment uses lower temperatures, less hazardous process and corrosion is not always a concern when the right choice is made with the combination of cation and anion of the IL and nally the regeneration of the IL makes the process feasible and economical.…”

Ionic liquids (ILs) have found applications in the pretreatment of waste lignocellulosic biomass by interacting with the carbohydrate molecules present in the biomass materials. Pretreatment is an essential step prior to biomass conversion into valuable chemicals, fuels, and many other value-added products. This comparative study mainly focused on the pretreatment ability of four ILs having acetate or triflate as a common anion with different cations. Among various studied ILs, diazabicyclo[5.4.0]undec-7-ene (DBU)-based acidic ionic liquid when used as a dual solvocatalyst showed significant structural modifications of the rice straw (RS) sample, through C6-O bond breakage assisted by the tertiary nitrogen in DBU cation. Structural modifications due to the pretreatment were confirmed through SEM, PXRD, and FTIR analysis. Elemental analysis confirmed that carbon content in original RS is reduced to 29% and 20% upon ionothermal treatment of RS with IL at 90 °C and 120 °C, respectively. Additionally, TGA indicated that further pyrolysis could be easier with the pretreated rice straw yielding biochar upto 9% thereby reducing wastes. Conversion of RS was found to be 60 % which reduced marginally to 50 % after three cycles of recycling IL. The findings of this work provide the proof of concept that studied ILs with high thermal stability and recyclability should act as a potential solvocatalyst in sustainable pretreatment and other biomass applications.
