Some of the same properties that make nanoparticles efficient drug carriers also contribute to their toxicity. For example, gold nanoparticles are known to interact with proteins through surface adsorption, forming a protein corona, which can be utilized for cargo loading and immune
Lipid-based carriers include both liposomes and micelles. Examples of gold nanoparticles are gold nanoshells and nanocages. [3] Different types of nanomaterial being used in nanocarriers allows for hydrophobic and hydrophilic drugs to be delivered throughout the body. [5]
In photothermal cancer therapy, many gold nanoparticle molecules are used in each test and they must all be uniform in size. Including PEG coating, the nanoparticles measured to be ~130 nm in diameter. [1] Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm. [2]
Metal nanoparticles are promising as carriers for drug delivery to the brain. Common metals used for nanoparticle drug delivery are gold, silver, and platinum, owing ...
Gold nanoparticles are being investigated as carriers for drugs such as Paclitaxel. [42] The administration of hydrophobic drugs require molecular encapsulation and it is found that nanosized particles are particularly efficient in evading the reticuloendothelial system .
[48] [49] In the case of patisiran, pretreatment with multiple anti-inflammatory drugs is used to minimize reactions to the nanoparticle. [50] There is currently little data available on the medical impact of intracellular delivery of novel chemical components of mRNA vaccines, such as SM-102 and ALC-0315, on both the short and long-term health ...
There are different types of drug delivery vehicles, such as polymeric micelles, liposomes, lipoprotein-based drug carriers, nano-particle drug carriers, dendrimers, etc. An ideal drug delivery vehicle must be non-toxic, biocompatible, non-immunogenic, biodegradable, [5] and must avoid recognition by the host's defense mechanisms [3].
Huang et al. investigated the feasibility of using gold nanorods for both cancer cell imaging as well as photothermal therapy. [2] The authors conjugated antibodies (anti-EGFR monoclonal antibodies) to the surface of gold nanorods, allowing the gold nanorods to bind specifically to certain malignant cancer cells (HSC and HOC malignant cells).
