Nanozymes Latest News

Researchers at the Indian Institute of Science (IISc.) recently developed an artificial metal-based nanozyme that can potentially be used to clamp down on abnormal blood clotting caused by conditions like pulmonary thromboembolism (PTE).

What are Enzymes?

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies.
They build some substances and break others down.
All living things have enzymes.
Our bodies naturally produce enzymes. But enzymes are also in manufactured products and food.

About Nanozymes

Nanozymes are nanomaterials that display enzyme-like characteristics.
They may be metallic, metal oxide-based, carbon-based, or of other types.

Nanozymes Advantages

They are less expensive and recyclable.
Nanozymes can also be easily manufactured and stored for long periods of time, further reducing their cost.
Typical inorganic enzymes require high temperature, high pressure, and extreme pH conditions. In contrast, nanozymes are able to work in environments closer to physiological conditions and respond to a range of external stimuli.
The most important advantage is the display of size/composition-dependent activity, meaning that nanozymes can be designed with a range of catalytic activity by simply varying shape, structure, and composition.
Nanozymes also have unique properties compared to other artificial enzymes, including integrated multi-functions not related to catalysis.
Nanoscale materials provide large surface areas, allowing greater ease in further modifications and bioconjugation.
The ability to self-assemble also mimics an important strategy in biology, meaning that biological components can be easily incorporated.

Nanozymes Applications

Nanozymes have a large range of applications for diagnostic medicine, targeted therapy, and biosensing.
In recent years, it has been found that various nanozymes have antioxidant activity, allowing them to simulate the endogenous antioxidant system and play an important role in cell protection.
Therefore, nanozymes can be applied in the treatment of reactive oxygen species (ROS)-related neurological diseases.
