“…LLCs possess idiosyncratic physicochemical properties and microstructures that make them a system of choice to incorporate drugs for biocompatible parenteral delivery [81]. LLC phases are developed by chirality, molecular shape, and micro-segregation effects [8,82]. Table 1 summarizes various characterization methods for LLCs and their application.…”

“…Liquid crystals (LC) are a unique category of drug delivery platform that possesses the orientation orders of both solid and liquid substances. They are found to imbibe the stable orientation order of solids and a flowy orientation of the liquids which puts them in a condensed state of matter [8]. Out of the two liquid crystals, namely thermotropic and lyotropic, the lyotropic type of liquid crystals are the ones that are used for the fabrication of drug delivery systems due to their ability to exhibit liquid crystallinity as a function of concentration [9].…”

“…Liquid crystals, or liquid crystalline structures, are materials that display intermediate properties of both solid and liquid states. , The uniqueness of this interplay allows liquid crystals to display properties that neither solids nor liquid could otherwise do alone. For example, a liquid crystal may flow as a liquid, but its molecules are oriented along a well-characterized length scale that resembles that of a solid state .…”

Filamentous bacteriophages (bacterial viruses) are semiflexible proteinous nanofilaments with high aspect ratios for which the surface chemistry can be controlled with atomic precision via genetic engineering. That, in addition to their ability to self-propagate and replicate a nearly monodisperse batch of biologically and chemically identical nanofilaments, makes these bionanofilaments superior to most synthetic nanoparticles and thus a powerful tool in the bioengineers’ toolbox. Furthermore, filamentous phages form liquid crystalline structures at high concentrations; these ordered assemblies create hierarchically ordered macro-, micro-, and nanostructures that, once cross-linked, can form hierarchically ordered hydrogels, hydrated soft material with a variety of physical and chemical properties suitable for biomedical applications (e.g., wound dressings and tissue engineering scaffolds) as well as biosensing, diagnostic assays. We provide a critical review of these hydrogels of filamentous phage, and their physical, mechanical, chemical, and biological properties and current applications, as well as an overview of limitations and challenges and outlook for future applications. In addition, we present a list of design parameters for filamentous phage hydrogels to serve as a guide for the (bio)engineer and (bio)chemist interested in utilizing these powerful bionanofilaments for designing smart, bioactive materials and devices.

Dendrite-free electrodeposition of lithium metal is necessary for the adoption of high energy-density rechargeable lithium metal batteries. Here, we demonstrate a mechanism of using a liquid crystalline electrolyte to suppress dendrite growth with a lithium metal anode. A nematic liquid crystalline electrolyte modifies the kinetics of electrodeposition by introducing additional overpotential due to its bulk-distortion and anchoring free energy. By extending the phase-field model, we simulate the morphological evolution of the metal anode and explore the role of bulk-distortion and anchoring strengths on the electrodeposition process. We find that adsorption energy of liquid crystalline molecules on a lithium surface can be a good descriptor for the anchoring energy and obtain it using first-principles density functional theory calculations. Unlike other extrinsic mechanisms, we find that liquid crystals with high anchoring strengths can ensure smooth electrodeposition of lithium metal, thus paving the way for practical applications in rechargeable batteries based on metal anodes.
