“…The above evidence provides the rationale behind this study that aimed to devise a technique to get the better of liquid preparation, through the concept of the nanocapsules impregnated mini bag. The impregnation of cotton fabric with the nanocapsules and microcapsules has been reported for long-lasting mosquito repellent and antibacterial effects 26,27 . However, such an approach may certainly be used to larvicidal control program on account of its sustainability.…”

The use pesticide is one of the indispensable means to combat mosquito borne diseases. However, the repeated use of synthetic pesticides has induced resistance in the vector pest along with undesirable impact on the environment. The biodegradability, non-persistent and user's safety are the root cause to prefer plant-derived pesticides to synthetic ones. The botanical based pesticides tend to degrade rapidly under the influence of several environmental factors. For the feasible application as pesticides, the plant products are formulated either as liquid or as purely solid. Despite well-established formulation technology in pesticide delivery, their handling trouble is being ignored. There is difficulty in liquid formulation of pesticide products, as they are prone to splashing and spillage, resulting in contamination, wastage and direct exposure to skin; whereas a solid formulation tends to produce dust. In the present work, cedarwood (Cedrus deodara) essential oil embedded pectin nanocapsules were produced. The nanocapsules were characterized according to their morphology, size, encapsulation efficiency and thermal stability. Furthermore, the nanocapsules were impregnated onto mini cotton tea bags to be employed as RTU (ready to use) formulation for treating the breeding sites of mosquitoes. The larvicidal activity of the bags treated with pectin-cedar wood nanocapsules was assessed against malaria vector, Anopheles culicifacies and 98% mortality was recorded till 4 weeks, this suggests its potential and hassle free applications in controlling mosquito vector. Global health threats, primarily due to mosquito borne diseases can devastate communities in social and economic terms and hinder development progress 1. Among the various vector borne diseases, malaria is the major public health issue, which transmits through the bite of Anopheles mosquitoes 2. According to the World Health Organization (WHO) 2019 report, malaria causes 228 million morbidity cases and 405,000 number of mortality 3. Anopheles culicifacies is alone accountable for 60-65% of the malaria burden 4. A Mosquito-borne disease remains a challenge since there is no vaccine, and further drug resistance is an increasing threat. Under these circumstances, vector control plays a vital role and often remains the only way to prevent disease outbreaks. The control of malaria vector, Anopheles, relies upon indoor residual spray (IRS) and insecticide treated nets (ITN) 5. Several other control tools have also been proposed including; nano pesticides, microbial pesticides (that are natural occurring bacteria, fungi and viruses) and pesticides of plant origin, which may act as repellents, oviposition deterrents and larvicides etc. 6,7. A new generation biotechnological tool in mosquito control program, based on genetically modified mosquitoes and sterile Insect Technique (SIT) is also being considered 7,8. Despite significant progress so far, further investigations are needed to determine if genetically modification based strategies can be an effective metho...

“…The results showed that nanocapsules were able to infiltrate the spacing of cotton textile fibers, including the fiber pores, thus leading to high washing durability (29% retention after 10 washing cycles). Others [ 187 ] included lemongrass oil loaded into emulsified CS NPs further physically-crosslinked with TPP (d ≈ 90 nm), which were then imprisoned into cotton fabric (plain-weave 112 g/m 2 , 60 ends per inch × 58 picks per inch) via dip-dry-curing while aimed at developing a durable anti-mosquito textile finishing. Acrylate was added as fabric adhesive to retain the nanogels adhered to the textile fibers.…”

Bioactivity of Chitosan-Based Particles Loaded with Plant-Derived Extracts for Biomedical Applications: Emphasis on Antimicrobial Fiber-Based Systems

Marine-derived chitosan (CS) is a cationic polysaccharide widely studied for its bioactivity, which is mostly attached to its primary amine groups. CS is able to neutralize reactive oxygen species (ROS) from the microenvironments in which it is integrated, consequently reducing cell-induced oxidative stress. It also acts as a bacterial peripheral layer hindering nutrient intake and interacting with negatively charged outer cellular components, which lead to an increase in the cell permeability or to its lysis. Its biocompatibility, biodegradability, ease of processability (particularly in mild conditions), and chemical versatility has fueled CS study as a valuable matrix component of bioactive small-scaled organic drug-delivery systems, with current research also showcasing CS’s potential within tridimensional sponges, hydrogels and sutures, blended films, nanofiber sheets and fabric coatings. On the other hand, renewable plant-derived extracts are here emphasized, given their potential as eco-friendly radical scavengers, microbicidal agents, or alternatives to antibiotics, considering that most of the latter have induced bacterial resistance because of excessive and/or inappropriate use. Loading them into small-scaled particles potentiates a strong and sustained bioactivity, and a controlled release, using lower doses of bioactive compounds. A pH-triggered release, dependent on CS’s protonation/deprotonation of its amine groups, has been the most explored stimulus for that control. However, the use of CS derivatives, crosslinking agents, and/or additional stabilization processes is enabling slower release rates, following extract diffusion from the particle matrix, which can find major applicability in fiber-based systems within ROS-enriched microenvironments and/or spiked with microbes. Research on this is still in its infancy. Yet, the few published studies have already revealed that the composition, along with an adequate drug release rate, has an important role in controlling an existing infection, forming new tissue, and successfully closing a wound. A bioactive finishing of textiles has also been promoting high particle infiltration, superior washing durability, and biological response.

The textile industry comprises technologies that transform synthetic or natural fibers into yarn, cloth, and felt for manufacturing clothing, upholstery, and household linens. The major public health threat in tropical and subtropical countries is mosquito‐borne malaria. Nowadays, the demand for insect repellent‐based textiles is continuously rising, as they are used for protection against diseases transmitted by mosquitoes. The present work reviews studies on the fabrication of insect repellent containing electrospun polymeric nanofibers as principal tools for protecting people against mosquito bites. Electrospinning technology is a remarkably facile technique for fabricating polymeric nanofiber devices. The technique is outlined and elucidated. The performance of insect repellent‐based polymeric nanofibers against mosquitoes is carefully reported and comprehensively reviewed in‐depth. Furthermore, the progress made on the mathematical modeling of the release rate of repellents through polymeric nanofiber devices is reviewed. The reviewed studies demonstrate that repellents can be released slowly from electrospun nanofibers, increasing the product's protection period against insects. The reviewed works suggest that electrospinning technology has led to an effective and facile methodology for fabricating functional nanofiber textiles with insect repellent. The reviewed studies showed that product‐based repellents can be effective not only against malaria but also against other mosquito‐borne diseases.
