INTRODUCTION

In the realm of nanotechnology, a field where the manipulation of matter at the nanoscale sparks innovations across industries, nanocapsules emerge as pint-sized marvels with vast potential. Measuring in the order of nanometers, these minute structures boast a distinctive core-shell architecture, where a core, housing various substances, is encapsulated within a thin polymeric, lipid, or inorganic membrane. The ingenious design of nanocapsules imparts a range of capabilities, from controlled release to targeted delivery, rendering them a focal point of exploration in diverse scientific domains. This article explores the multifaceted world of nanocapsules, delving into their composition, types, and applications that stretch from the realms of medicine to food preservation and imaging technologies. As we unravel the layers of this nanoscale innovation, we uncover the promises and challenges that accompany these tiny wonders, emphasizing their potential to reshape industries and revolutionize approaches to drug delivery and beyond. Nanocapsules, it seems, hold the key to unlocking a future where the extraordinary meets the infinitesimally small. Nanotechnology, the manipulation of matter at the nanoscale, has revolutionized various fields, including medicine, electronics, and materials science. Among the myriad of innovations, nanocapsules stand out as remarkable carriers of promise. These tiny structures, often measured in nanometers (billionths of a meter), have the potential to transform drug delivery, enhance food preservation, and revolutionize various industries. At the heart of nanocapsules lies their core-shell structure, a design that imparts unique properties and functionalities. Polymeric nanocapsules, often constructed from biocompatible materials such as poly(lactic-co-glycolic acid) (PLGA) or chitosan, showcase remarkable versatility. They can encapsulate both hydrophobic and hydrophilic compounds, making them invaluable in drug delivery and various other applications. Lipid nanocapsules, on the other hand, leverage lipids, employing structures like liposomes or solid lipid nanoparticles (SLNs). These lipid-based carriers find particular relevance in delivering lipophilic substances, and their structures mimic natural cell membranes, enhancing compatibility with biological systems. Inorganic nanocapsules, constructed from materials such as silica or gold, introduce a different dimension to the nanocapsule landscape. Their unique properties make them suitable for applications in imaging, sensing, and controlled drug release [1-10].
