Biodegradable polymeric fibrous non-woven materials are widely used type of scaffolds for tissue engineering. Their morphology and properties could be controlled by composition and fabrication technology. This work is aimed at development of fibrous scaffolds from a multicomponent polymeric system containing biodegradable synthetic (polylactide, polycaprolactone) and natural (gelatin, chitosan) components using different methods of non-woven mats fabrication: electrospinning and electro-assisted solution blow spinning. The effect of the fabrication technique of the fibrous materials onto their morphology and properties, including the ability to support adhesion and growth of cells, was evaluated. The mats fabricated using electrospinning technology consist of randomly oriented monofilament fibers, while application of solution blow spinning gave a rise to chaotically arranged multifilament fibers. Cytocompatibility of all fabricated fibrous mats was confirmed using in vitro analysis of metabolic activity, proliferative capacity and morphology of NIH 3T3 cell line. Live/Dead assay revealed the formation of the highest number of cell-cell contacts in the case of multifilament sample formed by electro-assisted solution blow spinning technology.

Introduction: Otitis media with effusion (OME) affects hearing, speech development, and quality of life (QoL) in children. The 'Blow, Breathe, Cough' (BBC) intervention promotes nasal, respiratory, and middle ear clearance through nose blowing, deep breathing, coughing, and hand hygiene. It shows promise in resolving OME but lacks randomized-controlled trial (RCT) evaluation.

Nanofibrous patches composed of chitosan (CS) present promising solutions for wound healing by supporting cell growth and enabling controlled drug release. This study introduces a new single-step microfluidic blow-spinning process that blends CS with polyethylene oxide (PEO) and crosslinks it with tripolyphosphate (TPP) using a series of laminar flow chips integrated into a blow-spinning apparatus. The microfluidic mixing between PEO and CS solutions at different concentrations was simulated with computational fluid dynamics (CFD).

Growing emphasis on green sustainability drives interest in eco-friendly packaging. This study first fabricates biodegradable zein-based nanofibers for active food packaging via green solution blow spinning, using zein/polyethylene oxide composites to enhance fiber uniformity and mechanical properties. Systematic modulation of acetic acid-water ratios and zein concentrations tailored nanofiber film characteristics.

Antimicrobial resistance arises from treatment non-adherence and ineffective delivery systems. Optimal wound dressings combine localized drug release, exudate management, and bacterial encapsulation through hydrogel-forming nanofibers for enhanced therapy. In this work, polylactic acid (PLA) and polyvinylpyrrolidone (PVP) fibers loaded with chlorhexidine (CHX) were developed using Solution Blow Spinning (SBS), a scalable electrospinning alternative that enables in situ deposition.

Benzodiazepines are commonly identified in drug overdose deaths worldwide. However, research on their effects on the most common necrophagous insect species is limited. In this context, the current study investigated the effects of clonazepam and flunitrazepam on the development cycle of Calliphora vicina Robineau-Desvoidy, 1830 (Diptera: Calliphoridae).
