“…The mechanical properties of the carboxylated butadiene-styrene rubber (xSBR), considerably improved after loading the HNTs 11 . The impact strength of the HNTs-epoxy nanocomposite 2,12 and HNTs-vinyl-ester composites also improved appreciably after loading of HNTs. HNTs also improved the tensile strength and Young's modulus of the chitosan 13,14 and PVA 15 nanocomposites films.…”

In nanotechnology different nano materials are used like carbon nanotubes, nanofluids, nanoparticles, nanoemulsions, nanocapsules, etc. Due to their toxic effects the results of these nano materials are not considered safe for humans and for the environment as well. Halloysite nanotubules (HNTs) having low cost are naturally occurring environmental friendly nanotubules. These are distinctive and handy materials formed by face weathering of aluminosilicate minerals having definite ratio of aluminum, silicon, hydrogen, and oxygen. HNTs have high mechanical strength and modulus. Due to these properties it is ideal for various applications; remediation of ecological contaminants, these are acting as a career for the delivery of drugs and various macro molecules, storage of H 2 gas, for catalytic conversions and for the processing of hydrocarbons. These are also used in anticancer therapy, sustained delivery for certain agents, as a template or nanoreactor for biocatalyst, in personal care, cosmetics and as environment caring. They are also used in the fabrication of high quality white-ware ceramics, nanotemplates and nano scale reaction bottles. Due to easy dispersability in polymer matrix, abundant availability and biocompatibility, HNTs are also used in different epoxy (EP) composites. In this review, we have tried to recap the different aspects of halloysites nanotubes for their use in different research fields.

“…Proteins and vesicles can be incorporated into chitosan matrix through codeposition mechanism. (Codeposition studies to create composite films with hard materials such as nanoparticles, carbon‐based nanomaterials, quantum dots, and implantable materials are beyond the scope of this report.) A drawback of using codeposition to entrap components in the chitosan hydrogel coating is that small components (e.g., proteins) may leak from the matrix.…”

Biology and electronics are both expert at for accessing, analyzing, and responding to information. Biology uses ions, small molecules, and macromolecules to receive, analyze, store, and transmit information, whereas electronic devices receive input in the form of electromagnetic radiation, process the information using electrons, and then transmit output as electromagnetic waves. Generating the capabilities to connect biology-electronic modalities offers exciting opportunities to shape the future of biosensors, point-of-care medicine, and wearable/implantable devices. Redox reactions offer unique opportunities for bio-device communication that spans the molecular modalities of biology and electrical modality of devices. Here, an approach to search for redox information through an interactive electrochemical probing that is analogous to sonar is adopted. The capabilities of this approach to access global chemical information as well as information of specific redox-active chemical entities are illustrated using recent examples. An example of the use of synthetic biology to recognize external molecular information, process this information through intracellular signal transduction pathways, and generate output responses that can be detected by electrical modalities is also provided. Finally, exciting results in the use of redox reactions to actuate biology are provided to illustrate that synthetic biology offers the potential to guide biological response through electrical cues.

“…Therefore, HNTs can be excellent substitutes for CNTs in developing new organic-inorganic nanocomposites. Importantly, HNTs exhibit potential application owing to their gibbsite octahedral sheet aluminum (innermost) and silicate (outermost) surfaces, which allow different chemical functionalities onto the internal and external surfaces [18][19][20]. For example, an inorganic micelle-like architecture with a hydrophobic aliphatic chain core and a hydrophilic silicate shell has been successfully achieved by selectively modifying the inner surface [21].…”
