Polymeric micelles are nanoscale colloidal carriers formed by the self-assembly of amphiphilic block copolymers in aqueous solutions, primarily used for drug delivery due to their ability to encapsulate hydrophobic drugs within their core. Their unique core-shell structure allows for improved solubility, stability, and controlled release of therapeutic agents, enhancing bioavailability and targeting capabilities.

Nanoscale colloidal carriers

Amphiphilic block copolymers are macromolecules composed of two or more chemically distinct polymer blocks, where at least one block is hydrophilic and another is hydrophobic, allowing them to self-assemble into various nanostructures in selective solvents. These copolymers are crucial in applications such as drug delivery, nanotechnology, and the stabilization of emulsions due to their ability to form micelles, vesicles, and other complex morphologies.

Amphiphilic Block Copolymers

Aqueous solutions are homogeneous mixtures where water acts as the solvent, dissolving various solutes to form a solution. They are essential in chemical reactions and biological processes, as water's polarity facilitates the dissolution and interaction of ionic and polar substances.

Core-shell structures are composite materials where one material (the shell) encapsulates another (the core), often to enhance or modify properties such as stability, functionality, or reactivity. These structures are crucial in fields like nanotechnology, drug delivery, and catalysis, where precise control over material interactions and properties is required.

Core-shell Structure

Solubility is the ability of a substance to dissolve in a solvent, forming a homogeneous mixture at a specific temperature and pressure. It is influenced by factors such as temperature, pressure, and the nature of the solute and solvent, and is crucial in fields ranging from chemistry to pharmacology.

Solubility

Stability refers to the ability of a system or entity to maintain its state or return to it after a disturbance, ensuring continuity and predictability over time. It is a fundamental characteristic sought in various fields such as physics, economics, and social sciences, where it implies resilience and equilibrium.

Stability

Controlled release is a technology used to deliver a drug or other active substances in a predetermined manner over a specified period of time, enhancing therapeutic efficacy and minimizing side effects. This approach is crucial in pharmaceuticals and agriculture, where it allows for precise targeting and sustained delivery of active compounds.

Controlled Release

Therapeutic agents are substances used to treat or manage diseases and medical conditions, encompassing a wide range of pharmaceuticals, biologics, and natural products. They work through various mechanisms to alleviate symptoms, cure diseases, or improve health outcomes, and their development involves rigorous testing for efficacy and safety.

Therapeutic Agents

Bioavailability is the proportion of a drug or other substance that enters the bloodstream when introduced into the body and is thus able to have an active effect. It is a critical pharmacokinetic property that influences the efficacy and safety of medications and nutrients.
