“…Metal‐organic frameworks (MOFs) have also been used in the functionalization of nanofibers by the LbL method. [ 171 ] For example, Jiamjirangkul and colleagues [ 172 ] used different approaches for the preparation of functionalized chitosan/PVA nanofibers (CNFs) with the MOF copper‐1,2,5‐benzenetricarboxylic‐acid (Cu‐BTC). The three approaches were: i) direct mixing of Cu‐BTC MOF with the polymeric solution and electrospinning; ii) in situ formation of Cu‐BTC MOF in CNFs; and iii) deposition of Cu‐BTC MOF on the surface of CNFs by the LbL method.…”

Micro‐ and nanofibers produced by electrospinning and solution blow spinning (SBS) are highly suitable platforms for diverse applications due to their advantageous properties, including the high surface area to volume ratio, high porosity, and flexibility. To render them additional functionalities, distinct pre‐ or post‐modification processes have been proposed for modifying such micro‐ and nanofibers with 0D, 1D, 2D, and 3D nanostructures. The pre‐modification requires the addition of 0D–3D nanostructures (or their precursors) into the polymeric phase before the spinning process, which can demand laborious solubilization and requires changes in experimental spinning parameters, with impact on morphology, spinnability, and properties. Post‐modification methods, on the other hand, enable the fabrication of composite fibers without the need to optimize the spinning parameters, allowing a simple and efficient surface modification. Herein, recent advances on post‐modification methods of spun fibers, including wet chemistry, grafting, crosslinking, click chemistry, oxidations, hydrolysis and reduction strategies, dip‐coating, layer‐by‐layer, electro/air‐spray, atomic layer deposition, and plasma techniques aiming at the surface functionalization with 0D–3D nanostructures are surveyed. Recent results, trends, and challenges on the application of such surface‐modified fibers for environmental, industrial, and medical applications, including as adsorbent and filtering membranes, catalysts for pollutants degradation, and wearable sensors are examined.

“…Em comparação a outros materiais, como metais e cerâmicas, é relativamente simples modificar a morfologia e a composição química da superfície de fibras poliméricas. 47 Diferentes metodologias podem ser empregadas visando a inserção/remoção de grupamentos funcionais 47 ou incorporação de outros materiais, como: polímeros, 14,17 nanopartículas, 18,48 nanomateriais à base de carbono, 49,50 supramoléculas, 51,52 biomoléculas, 53,54 entre outros. Essas modificações nas fibras eletrofiadas podem ser feitas empregando-se abordagens de pré ou pós-tratamento.…”

On-demand drug-delivery systems using nanofibers are extensively applicable for customized drug release based on target location and timing to achieve the desired therapeutic effects. A nanofiber formulation is typically created for a certain medication and changing the drug may have a significant impact on the release kinetics from the same delivery system. Nanofibers have several distinguishing features and properties, including the ease with which they may be manufactured, the variety of materials appropriate for processing into fibers, a large surface area, and a complex pore structure. Nanofibers with effective drug-loading capabilities, controllable release, and high stability have gained the interest of researchers owing to their potential applications in on-demand drug delivery systems. Based on their composition and drug-release characteristics, we review the numerous types of nanofibers from the most recent accessible studies. Nanofibers are classified based on their mechanism of drug release, as well as their structure and content. To achieve controlled drug release, a suitable polymer, large surface-to-volume ratio, and high porosity of the nanofiber mesh are necessary. The properties of nanofibers for modified drug release are categorized here as protracted, stimulus-activated, and biphasic. Swellable or degradable polymers are commonly utilized to alter drug release. In addition to the polymer used, the process and ambient conditions can have considerable impacts on the release characteristics of the nanofibers. The formulation of nanofibers is highly complicated and depends on many variables; nevertheless, numerous options are available to accomplish the desired nanofiber drug-release characteristics.
