Electrospun composite membranes of ethyl cellulose and MXene (TiCT): Biocompatible platforms for enhanced drug delivery and antibacterial wound healing.

Ethyl cellulose (EC), a degradable cellulose derivative, served as a primary component in membranes fabricated by electrospinning for in vitro drug delivery applications. An effective strategy to enhance drug release was incorporating high-surface-area nanomaterials into polymeric drug carriers, which facilitated drug attachment to both the polymer matrix and additive surfaces, promoting release. MXene (TiCT) demonstrated promising potential in improving tensile mechanical properties, antibacterial activity, and curcumin (Cur) release performance of EC membrane.

Multifunctional poloxamer-based thermo-responsive hydrogel loaded with human lactoferricin niosomes: study on anti-bacterial activity, accelerate wound healing, and anti-inflammation.

Chronic wound infections are attributed to delayed tissue repair, which remains a major clinical challenge in long-term health care. Particularly, infections with antibiotic resistance have more serious effects on health, often resulting in unsuccessful treatments. Thus, antimicrobial peptide (AMP)-based therapy holds promise as a potential therapeutic approach to overcoming drug resistance.

A MAX phase (TiAlC) as a performance enhancer for poly(lactic acid) electrospun membranes in steam generation and solar desalination.

Clean water and sanitation issues motivate researchers to develop water evaporators for freshwater generation. The composite membrane evaporator was electrospun herein based on poly(lactic acid) (PLA) and TiAlC MAX phase as a property enhancer. As a precursor for the MXenes synthesis, the MAX phase has never been explored with PLA for water evaporator potential.

Ethyl cellulose composite membranes containing a 2D material (MoS) and helical carbon nanotubes for efficient solar steam generation and desalination.

With the increasing water consumption, water evaporators have been investigated for clean water production. Herein, the fabrication of electrospun composite membrane evaporators based on ethyl cellulose (EC), with the incorporation of light-absorption enhancers 2D MoS and helical carbon nanotubes, for steam generation and solar desalination is described. Under natural sunlight, the maximum water evaporation rate was 2.

Preparation and Characterization of PLG Microparticles by the Multiple Emulsion Method for the Sustained Release of Proteins.

Rapid release and diminished stability are two of the limitations associated with the growth factors that are essentially used in dental applications. These growth factors are employed to enhance the quality and quantity of tissue or bone matter during regeneration. Therefore, drug delivery devices and systems have been developed to address these limitations.

Characteristic Structural Knowledge for Morphological Identification and Classification in Meso-Scale Simulations Using Principal Component Analysis.

Meso-scale simulations have been widely used to probe aggregation caused by structural formation in macromolecular systems. However, the limitations of the long-length scale, resulting from its simulation box, cause difficulties in terms of morphological identification and insufficient classification. In this study, structural knowledge derived from meso-scale simulations based on parameters from atomistic simulations were analyzed in dissipative particle dynamic (DPD) simulations of PS--PI diblock copolymers.

Preparation of injectable hydrogels from temperature and pH responsive grafted chitosan with tuned gelation temperature suitable for tumor acidic environment.

In this present work, stimuli responsive polymers that can respond to the temperature and pH of the environment were prepared. A series of temperature responsive diblock copolymers based on poly(ethylene glycol) methyl ether (mPEG) and ε-caprolactone (CL) were synthesized. Subsequently, the diblock copolymers were grafted onto chitosan, a pH responsive biopolymer.

Binding interactions between lysozyme and injectable hydrogels derived from albumin-pH/thermo responsive poly(amino urethane) conjugates in aqueous solution.

Injectable hydrogels are alternative materials for drug and protein delivery in biomedical applications, which can potentially eliminate the need of surgical implantation in the treatment procedures. Prior to administration, such hydrogels, in a liquid state, must demonstrate good interactions with the incorporated molecules to maintain the sustain release of active agents and to avoid unappreciative burst release. The injectable hydrogels derived from BSA-pH/temperature responsive poly(amino urethane) conjugates have been reported to demonstrated good sustainability for delivery of lysozyme, both in vitro and in vivo.

Albumin-conjugated pH/thermo responsive poly(amino urethane) multiblock copolymer as an injectable hydrogel for protein delivery.

Albumin-conjugated pH and thermo responsive poly(amino urethane) multiblock copolymers are synthesized. The aqueous solution of the conjugate exhibits pH/temperature dependent sol-gel phase transitions that can be tuned by changing solution concentration and albumin composition. The gel window well covers the physiological condition allowing the flowing liquid to readily form the solid gel under the back of the Sprangue-Dawley (SD) rats.

Polyethylene nanocomposite heat-sealants with a versatile peelable character.

A novel heat-sealing performance is achieved by polyethylene (PE) nanocomposites reinforced by ethylene vinyl acetate (EVA) and montmorillonite (MMT). Appropriate nanocomposite design leads to hermetic seals with a general peelable/easy-open character across the broadest possible sealing temperature range. Observations of the fracture seal surfaces by infrared spectroscopy and electron microscopy reveal that this behavior originates from a synergistic effect of the EVA copolymer and the montmorillonite clay nanofiller.
