“…Examples of simple ILs are shown in Figure 1 . Unsurprisingly, currently this class of organic substances is widely utilized in such different scientific and industrial areas as chemical synthesis (both as media and catalysts) ( 9 , 11 , 19–21 ), electrochemistry ( 10 , 12 , 15 , 22 , 23 ), extraction ( 24–28 ), biomass processing ( 13 , 29 , 30 ) and biotechnology ( 17 , 31 , 32 ).…”

Operations with nucleic acids are among the main means of studying the mechanisms of gene function and developing novel methods of molecular medicine and gene therapy. These endeavours usually imply the necessity of nucleic acid storage and delivery into eukaryotic cells. In spite of diversity of the existing dedicated techniques, all of them have their limitations. Thus, a recent notion of using ionic liquids in manipulations of nucleic acids has been attracting significant attention lately. Due to their unique physicochemical properties, in particular, their micro-structuring impact and tunability, ionic liquids are currently applied as solvents and stabilizing media in chemical synthesis, electrochemistry, biotechnology, and other areas. Here, we review the current knowledge on interactions between nucleic acids and ionic liquids and discuss potential advantages of applying the latter in delivery of the former into eukaryotic cells.

“…Los LI son sales orgánicas compuestas por pares de cationes y aniones que tienen estructuras asimétricas como se observa en la tabla 3, lo que explica sus bajos puntos de fusión (≤ 100 • C). Se denominan "designer solvents" ya que su miscibilidad, punto de fusión, viscosidad, basicidad de enlace de hidrógeno y polaridad se pueden adaptar ajustando los componentes de cationes y/o aniones [7], [34]. Generalmente, tienen alta estabilidad térmica y química, amplia región líquida, presión de vapor insignificante, reciclabilidad y no inflamabilidad, considerándose solventes amigables con el medio ambiente y eficientes para el procesamiento de la biomasa.…”

En las últimas décadas, la aplicación de líquidos iónicos (LI) como pretratamiento de la biomasa (BM) residual previo a la reacción de hidrólisis, ha demostrado ser un sistema eficiente para mejorar los rendimientos hacia la obtención de monosacáridos. Una mayor recuperación de monosacáridos, se traduce en un mayor rendimiento en la producción de biocombustibles pudiendo volver a esta industria rentable. En este contexto, la presente revisión bibliográfica analiza las características fisicoquímicas, métodos de síntesis, condiciones de disolución con aplicación de variables tales como: relación LI: BM, temperatura y tiempo. Además, se realiza un análisis comparativo de los resultados de procesos de hidrólisis ácida tradicional con respecto a los obtenidos con la aplicación de líquidos iónicos, aumentado en la mayoría de los casos sus rendimientos de reacción. Finalmente, se mencionan algunas técnicas de recuperación y reciclaje, que permitan reducir los costos del proceso, de manera que este sea económicamente rentable.

“…Small cationic chained (C1-C4) ILs possess a greater cellulose solubility, followed with acetate containing imidazolium-based ILs. The high solubility has been associated with the hydrogen bonding basicity, less steric hindrance and the ability to break interand intramolecular hydrogen bonds [33]. The hydrogen bond acceptor strength [125] of the anion appears to be the dominating aspect, while the cellulose-cation interaction may occur either via hydrogen bonding or charge delocalization [126][127][128][129][130].…”

Considering its availability, renewable character and abundance in nature, this review assesses the opportunity of the application of biomass as a precursor for the production of carbon-based nanostructured materials (CNMs). CNMs are exceptionally shaped nanomaterials that possess distinctive properties, with far-reaching applicability in a number of areas, including the fabrication of sustainable and efficient energy harnessing, conversion and storage devices. This review describes CNM synthesis, properties and modification, focusing on reports using biomass as starting material. Since biomass comprises 60–90% cellulose, the current review takes into account the properties of cellulose. Noting that highly crystalline cellulose poses a difficulty in dissolution, ionic liquids (ILs) are proposed as the solvent system to dissolve the cellulose-containing biomass in generating precursors for the synthesis of CNMs. Preliminary results with cellulose and sugarcane bagasse indicate that ILs can not only be used to make the biomass available in a liquefied form as required for the floating catalyst CVD technique but also to control the heteroatom content and composition in situ for the heteroatom doping of the materials.
