Targeted delivery is believed to improve efficacy while reducing side-effects. When implementing a targeted release system, the following design criteria for the system must be taken into account: the drug properties, side-effects of the drugs, the route taken for the delivery of the drug, the targeted site, and the disease.
Recently, however, some studies have shown that certain nanoparticle environmental toxicity effects aren't apparent until nanoparticles undergo transformations to release free metal ions. Under aerobic and anaerobic conditions, it was found that copper, silver, and titanium nanoparticles released low or insignificant levels of metal ions.
Traditionally, LNPs are composed of four indispensable lipid components: an ionizable amino lipid that aids in both escaping the endosomes and binding nucleic acids to the particle, an amphipathic phospholipid that promotes fusion with the target cell and endosomes, cholesterol to enhance nanoparticle stability, and a polyethylene glycol lipid ...
Development of solid lipid nanoparticles is one of the emerging fields of lipid nanotechnology (for a review on lipid nanotechnology, see [16]) with several potential applications in drug delivery, clinical medicine and research, as well as in other disciplines. Due to their unique size-dependent properties, lipid nanoparticles can possibly ...
SLNs can be made by replacing the liquid lipid oil used in the emulsion process with a solid lipid. In solid lipid nanoparticles, the drug molecules are dissolved in the particle's solid hydrophobic lipid core, this is called the drug payload, and it is surrounded by an aqueous solution. [6]
The overall drug consumption and side-effects may be lowered significantly by depositing the active pharmaceutical agent in the diseased region only and in no higher dose than needed. Targeted drug delivery is intended to reduce the side effects of drugs in tandem decreases in consumption and treatment expenses.
The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
The SNALPs ranged from 71 – 84 nm in size and were composed of synthetic cholesterol, phospholipid DSPC, PEG lipid PEGC-DMA, and cationic lipid DLinDMA at the molar ratio of 48:20:2:30. [10] The results confirm complete protection against viremia and death in guinea pigs when administered a SNALP-siRNA delivery system after diagnosis of the ...
