The bulk of metal ions are carcinogens that significantly harm human health
by producing free radicals. Therefore, the need for quick and accurate metal ion
detection has been a matter of concern. However, the most dangerous metal ions are
cadmium, arsenic, mercury chromium, and lead. Heavy metals are indestructible.
Instead, they interact with living things directly or indirectly via the food chain. Metal
ions have the potential to directly disrupt metabolic processes or to change into more
hazardous forms inside the body. Nanotechnology is known as an emerging field that
has been utilized for heavy metal analysis and removal from intricate matrices.
Numerous methods based on nanomaterials have been developed for the analysis of
heavy metals, including electrochemical, colorimetric, fluorescent, and biosensing
technologies. As a result, in recent decades, there has been significant growth in the
quest for more systematic nano-vesicular systems, like nanoliposomes, with elevated
biocompatibility properties and directed releases. Additionally, nanoliposome have
various applications such as drug delivery in the pharmaceutical industry, storage of
food mainly cheeses, and dairy products for a long time in the food industry and
cosmetics industry
