Gastrointestinal infections, which are caused primarily by pathogenicbacteria, remain a significant global health challenge. Their resilience isreinforced by various physical, biological, and biopharmaceutical barriers thatcomplicate conventional therapeutic strategies. This review delves into theintricate landscape of managing these infections, addressing microbiotaimbalances, the emergence of multidrug-resistant strains, and the impact ofdysbiosis and antibiotic overuse. Faced with these challenges, traditionaltherapies often fail, which is hindered by low bioavailability, prolongedregimens, and a growing risk of resistance. In this context, nanotechnologyapplied to antimicrobial peptides (AMPs) has emerged as a promisingsolution to enhance their stability and targeted delivery. Through a criticalapproach, diverse nanocarriers and their efficacy against intestinal pathogensare evaluat...

In recent years, nanotechnology has made significant progress in various fields, including agriculture, where nanofertilizers play a pioneering role in improving crop productivity and reducing environmental pollution. In this study, a controlled-release nanofertilizer was developed using chitosan nanoparticles loaded with nitrogen (N), phosphorus (P), and potassium (K). The chitosan nanoparticles (CS-NPs) were prepared via an ionic gelation method using sodium tripolyphosphate and characterized by scanning transmission electron microscopy and infrared spectroscopy. The results revealed that the nanoparticle size ranged from 17.21 nm to 18.32 nm. The controlled release of N, P, and K was evaluated over 240 hours. The nanofertilizer was then applied foliage to Solanum tuberosum seedlings under greenhouse conditions. The findings indicated that the 0.25% chitosan nanofertilizer formulation ...
