What are Theranostic nanoparticles?


What are Theranostic nanoparticles?

Theranostic nanoparticles are multifunctional nanosystems, which are well-designed for more specific and personalized disease management by combining diagnostic and therapeutic capabilities into one single biocompatible and biodegradable nanoparticle (1).

How nanoparticles are used in bioimaging?

Nanoparticle fluorescence imaging has been used in gene detection, protein analysis, enzyme activity evaluation, element tracing, cell tracking, early stage disease diagnosis, tumor related research, and monitoring real time therapeutic effects.

What is Nano imaging agent?

Nano-imaging agents are NPs, such as quantum dots, that express bright fluorescence or luminescence, and can be detected through optical imaging methods to obtain wavelength (in nanometers) absorbance data or develop an image.

What are the biochemical applications of nanomaterials?

Due to nanoscale effects and increased surface area, nanomaterials have been investigated as promising tools for the advancement of diagnostic biosensors, drug and gene delivery, and biomedical imaging.

What is Theranostic treatment?

Theranostics is the term used to describe the combination of using one radioactive drug to identify (diagnose) and a second radioactive drug to deliver therapy to treat the main tumor and any metastatic tumors.

What is theranostics Wikipedia?

Theranostics. Theranostics is a personalised approach to treating cancer, using similar molecules for both imaging (diagnosis) and therapy. The word “theranostics” is derived from the combination of the words “therapeutics” and “diagnostics”.

Which metal is used with nanoparticles for antibiotic delivery?

Although research has been expanded over the recent years to other less-common metals, the most widely used materials in metal-based nanoparticles include silver, gold, copper, iron, and zinc [17,18,19].

How do imaging agents work?

A variety of imaging agents are used to visualize cellular activity, such as the chemical processes involved in metabolism, oxygen use or blood flow. In nuclear medicine, which is a branch of molecular imaging, the imaging agent is a radiotracer, a compound that includes a radioactive atom, or isotope.

What are medical imaging agents?

Imaging Agents are used to visualise the function of internal organs, perform clinical analysis and medical procedures. Diagnostic imaging is used to produce visual information about the internal parts of the human body and helps to diagnose the disease state.

Why are nanoparticles used in sunscreen?

Despite clumping together when mixed into sunscreen, nanoparticles of titanium dioxide and zinc oxide not only retain their highly effective UV light-absorbing capacity, but also absorb and scatter visible light, rendering them transparent on the skin.

What are nano molecules?

Nano molecules (NMs) are nanoparticles with a compositionally precise number of metal atoms protected by thiolate ligands. They show interesting size dependent properties that differ from those of bulk metal and single atoms. Gold NMs are the most studied, due to their superior stability.
