Is nanotechnology being used in food?

Applications of nanotechnology have emerged with increasing need of nanoparticle uses in various fields of food science and food microbiology, including food processing, food packaging, functional food development, food safety, detection of foodborne pathogens, and shelf-life extension of food and/or food products.

Why is nanotechnology important in medicine?

Since different cell types have unique properties, nanotechnology can be used to “recognise” cells of interest. This allows associated drugs and therapeutics to reach diseased tissue while avoiding healthy cells.

How does nanotechnology help preserve food?

Encapsulation of effective molecules or components in NSMs can enhance the bio-availability and solubility of coloring agents and nutritional ingredients such as minerals and vitamins, thus facilitating controlled release and protecting biologically active substances and micro-nutrients during their processing.

Why are nanoparticles used in food?

ZnO nanoparticles may also be utilized in food packaging as antimicrobial agents to prevent contamination of foods with harmful bacteria37 or as ultraviolet (UV) light absorbers to protect foods that are sensitive to UV light exposure.

How can nanotechnology affect our health when we use them?

The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems. The pulmonary injury and inflammation resulting from the inhalation of nanosize urban particulate matter appears to be due to the oxidative stress that these particles cause in the cells.

What are the health and safety concerns about nanotechnology?

What are the health and safety concerns about nanotechnology?

• changes in lung cells (in vitro) and tissue when exposed to carbon nanotubes.
• pulmonary inflammation and neuro-immune responses when exposed to nano or ultrafine titanium dioxide.

What is Nano treatment?

Nano infusion therapy is a non-invasive effective treatment for skin conditions including fine lines, wrinkles, scarring and pigmentation. Nano infusion therapy offers immediate and long term results that enhances product absorption and drives active ingredients deep into the skin for optimal skin restoration.

How nanotechnology is used in chemotherapy?

The traditional use of nanotechnology in cancer therapeutics has been to improve the pharmacokinetics and reduce the systemic toxicities of chemotherapies through the selective targeting and delivery of these anticancer drugs to tumor tissues.

What is Nanomedicine used to treat?

Since 1995, it has been used to treat adult cancers including ovarian cancer, multiple myeloma and Karposi’s sarcoma (a rare cancer that often affects people with immune deficiency such as HIV and AIDS). Currently, there is a stream of new nanomedicine treatments for adult cancers in clinical trials (trials in humans), or on the market.

What are the modifications that nanotechnology introduces in medicines?

Changes in toxicity, solubility and bioavailability profile are some of the modifications that nanotechnology introduces in medicines. In the last decades, we have assisted to the translation of several applications of nanomedicine in the clinical practice, ranging from medical devices to nanopharmaceuticals.

What are the issues to consider when developing nanomedicine products?

General issues to consider during the development of nanomedicine products including physicochemical characterization, biocompatibility, and nanotoxicology evaluation, pharmacokinetics and pharmacodynamics assessment, process control, and scale-reproducibility (Figure 2) are discussed in the sections that follow. Figure 2.

Are nanomedicines the future of clinical trials?

Over the last decades, nanomedicines have been successfully introduced in the clinical practice and the continuous development in pharmaceutical research is creating more sophisticated ones which are entering in clinic trials.
