nanoparticles in medicine review
Clinical trials are one kind of study that has been carried out to assess the effectiveness of NP-mediated diagnosis and/or therapy and quantify the therapeutic benefit to patients.
However, before clinical trials can be created, a number of additional difficulties must be overcome.
Many requirements must be completed before NPs may be regarded as therapeutically useful.
All of these features are required for every medicinal or imaging agent (whether imaging-or therapy-related).
These properties have been examined in vitro and in vivo, and the findings show that they are difficult to predict based on individual particle properties.
They are the product of the interaction of numerous elements such as particle size, shape, substance, and coating.
Because of this interaction, maximizing NP qualities in isolation is unlikely; instead, particles should undergo extensive in vitro and in vivo preclinical testing that accounts for all of these impacts before being employed in clinical investigations.
Producing NPs on a large scale is also a significant difficulty.
The great majority of studies either develop their own NP formulations in-house or employ commercial particles manufactured on a large enough scale for laboratory testing.
These preparations may be rather costly; for example, raw unconjugated nanoparticles can cost up to $10,000/gram of gold, and particles that have been functionalized to the customer's demands can cost even more.
While developing novel techniques, it is critical to consider how revolutionary nanoparticles may be properly scaled up.
Showing clinical proof of concept, on the other hand, should attract the attention of major pharmaceutical corporations and offer them more motivation to compete.
The health of individuals and populations in the twenty-first century depends on
Clinical medicine focuses on individual health, while public health promotes, protects, and maintains the health of groups or communities.
