Solid lipid nanoparticles (SLNs) have emerged as a promising drug delivery system due to their various advantages, including improved bioavailability and controlled drug release. Triglycerides, such as glyceryl monostearate and glyceryl tripalmitate, are commonly used in SLNs as a solid matrix for drug encapsulation and controlled release. Waxes like cetyl palmitate and beeswax are also utilized in SLNs to enhance drug stability and regulate drug release. The use of such lipids in SLNs has demonstrated great potential for targeted drug delivery and treatment of various diseases. AxisPharm provides more than 5000 high-purity polyethylene glycol (PEG) linkers or ADC linkers with different linker lengths, bearing various reactive groups.

Introduction of Solid Lipid Nanoparticles (SLNs)
Solid lipid nanoparticles are lipid-based colloidal systems consisting of a solid lipid matrix that is surrounded by a stabilizing emulsifier layer, making them suitable for the delivery of hydrophilic, lipophilic, and poorly soluble drugs.
The primary components of solid lipid nanoparticles are triglycerides and waxes. Triglycerides are the most commonly used solid lipid component in these nanoparticles. They often provide a solid matrix for drug encapsulation and controlled release, which is a critical factor in drug delivery.
In contrast, waxes, such as cetyl palmitate or beeswax, are used to control drug release and stability. These waxes are incorporated into the solid lipid nanoparticle matrix to stabilize the lipid phase and protect the entrapped active ingredient. Furthermore, they help in the binding of the matrix with the drug molecule, reducing drug leakage during storage and transport.
The Benefits of Solid Lipid Nanoparticles (SLNs)
Solid lipid nanoparticles are becoming increasingly popular for drug delivery applications due to their numerous benefits. Some significant advantages of solid lipid nanoparticles:
Improved Bioavailability:
Solid lipid nanoparticles are used to improve the bioavailability of drugs, particularly those that are poorly soluble in water. The lipid-based matrix of solid lipid nanoparticles enables the encapsulation of hydrophobic drugs, increasing their solubility in aqueous environments. This results in improved drug absorption and bioavailability.
In addition, colloidal drug delivery systems, such as solid lipid nanoparticles, provide a large surface area which enhances drug uptake by the cells, leading to increased absorption.
Controlled Drug Release:
Drug release from solid lipid nanoparticles is controlled, as the active ingredient is encapsulated within the solid lipid matrix. The release of the drug from the matrix depends on the physic-chemical properties of the lipid matrix, such as its crystallinity, particle size, and surface area.
The solid lipid nanoparticle matrix can be designed in such a way that the active ingredient is released in a controlled manner over an extended period. Therefore, the drug can reach the targeted site, and the desired therapeutic effect can be achieved.
Targeted Drug Delivery:
One of the essential benefits of solid lipid nanoparticles is targeted drug delivery. The emulsion layer surrounding the lipid nanoparticle enhances the interaction of the nanoparticle with the targeted site, improving the selectivity of drug delivery.
Furthermore, by modifying the nanoparticle surface with specific ligands, the interaction of the nanoparticle with the targeted cells is enhanced, reducing the interaction of the nanoparticle with the non-targeted cells.
