Abstract
Background: The concept of nutraceuticals has gained increased attention recently as it
is based on using natural substances for therapeutic applications. However, limitations such as low
bioavailability have restricted the use of these substances thus far. Nanoencapsulation of nutraceuticals
has been proposed as a promising solution to circumvent such issues by increasing their bioavailability
and targeting their release. Metal and metal oxide nanoparticles are amongst the inorganic
nanocarriers that have been studied for their ability to encapsulate nutraceuticals.
Objectives: The aim of this article is to provide an overview of metal and metal oxide nanoparticles
and their synthesis and applications. Furthermore, the conjugation of these nanoparticles with nutraceuticals
will be discussed, along with their potential applications.
Conclusion: It has been observed that the conjugation of nutraceuticals with metal nanoparticles resulted
in the cumulative properties of both these factors with increased effectiveness. Such advancements
are crucial for nutraceutical use in important theranostic applications that combine diagnosis
and therapy.
Keywords:
