Neurological disorders that are characterized by unpredictable seizures affect people of all ages. We proposed the use of nanocarriers such as halloysite nanotubes to penetrate the blood-brain barrier and effectively deliver the payload over an extended time period. These 50-nm diameter tubes are a natural biocompatible nanomaterial available in large quantities. We proved a prolonged gradual drug delivery mechanism by the nanotube encapsulating rhodamine isothiocyanate and then ionomycin into brain microvascular endothelial cells (BMVECs). Through delayed diffusion, the nanotubes effectively delivered the drug to the primary BMVECs without killing them, by binding and penetration in time periods of 1 to 24 h.

This study aims to fabricate bio-nanocomposite films using a solution-casting method based on sodium alginate (SA) and xanthan gum (XG). These films are reinforced with hybrid Halloysite nanotubes (Hal) containing zinc oxide nanoparticles (ZnO-Hal) and licorice root extract (ZnO-Hal-LRE) in various concentrations. These films were characterized using FT-IR, XRD, and scanning electron microscopy (SEM).

Lidocaine is an analgesic agent frequently incorporated in topical formulations intended for application in minor surgical procedures or relieving neuropathic pain associated with numerous conditions, including post-herpetic neuralgia or diabetic peripheral neuropathy. In this study, Pickering o/w emulsions with halloysite nanotubes as a stabilizing agent and lidocaine incorporated in the internal phase were formulated with the use of the Quality by Design (QbD) approach. The selected emulsions were transformed into semisolid gels with poloxamer 407 as a thickening agent, and investigated for rheological and textural properties, indicating the mechanical features of the obtained gels.

Superabsorbent materials (SAMs), featuring a three-dimensional (3D) hydrophilic polymer network, can absorb and retain water up to thousands of times their own weight, even under pressure. This makes them indispensable in various fields, including hygiene products and agriculture. The water absorption capacity of SAMs is influenced by the presence of hydrophilic groups and a swellable network structure.

Lithium-sulfur batteries are expected to supersede existing lithium-ion batteries due to the high theoretical energy density of sulfur cathodes (positive electrodes). Unfortunately, inefficient redox reactions and the "shuttle effect" hinder their commercial development. Assembling high-performance nanostructured sulfur host materials into a sulfur cathode presents a viable solution.

2,4,6-Trinitrophenol (TNP) is explosive, toxic, ecological, and a human health hazard and is resistant to degradation. It can cause symptoms such as headache, loss of appetite, dizziness, fever, nausea, diarrhea, and vomiting when inhaled. In this study, we aimed to develop a new halloysite nanotube anchored with pyrene moieties () for the sensitive determination of TNP in soil, wastewater, and food samples using fully aqueous media.
