What do you understand by Theranostics?
What do you understand by Theranostics?
Theranostics is a combination of the terms therapeutics and diagnostics. 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 are the 3 types of nanoparticles?

What are polymeric nanoparticles?
Polymeric nanoparticles (NPs) are particles within the size range from 1 to 1000 nm and can be loaded with active compounds entrapped within or surface-adsorbed onto the polymeric core. Polymeric NPs have shown great potential for targeted delivery of drugs for the treatment of several diseases.
What is a nanocarrier used for?
A nanocarrier is nanomaterial being used as a transport module for another substance, such as a drug. Commonly used nanocarriers include micelles, polymers, carbon-based materials, liposomes and other substances.
Who first coined the term theranostics?
Although the term theranostics was reported to be coined by John Funkhouser in 1998 (1) to describe a material that combines the modalities of therapy and diagnostic imaging, this basic principle had been applied to imaging and treating thyroid diseases for more than 50 years (2).
Who coined theranostics?
The concept of “theranostics” was coined by the US consultant John Funkhouser, in a press release from the company Cardiovascular Diagnostics in August 1998, to describe a material that allows the combined diagnosis, treatment and follow up of a disease (1).
What is the size of nanoparticle?
nanoparticle, n—in nanotechnology, a sub-classification of ultrafine particle with lengths in two or three dimensions greater than 0.001 micrometer (1 nanometer) and smaller than about 0.1 micrometer (100 nanometers) and which may or may not exhibit a size-related intensive property.
What is the difference between nanotechnology and nanobiotechnology?
When a distinction is intended, though, it is based on whether the focus is on applying biological ideas or on studying biology with nanotechnology. Nanobiotechnology, on the other hand, refers to the ways that nanotechnology is used to create devices to study biological systems.
What are polymeric nanoparticles made of?
2.2 Polymeric Nanoparticles Polymeric nanoparticles have a matrix architecture composed of biodegradable and biocompatible polymers of synthetic or natural origin (Fig. 23.3). The most widely used synthetic polymers are polylactide, polylactide–polyglycolide copolymers, polycaprolactones, and polyacrylates.
What are polymeric nanoparticles in drug delivery?
Polymeric nanoparticles stand out as a key tool to improve drug bioavailability or specific delivery at the site of action. The versatility of polymers makes them potentially ideal for fulfilling the requirements of each particular drug-delivery system.
How Nanoencapsulation is done?
Nanoencapsulation by coacervation is carried out by preparing an aqueous polymer solution (1–10 %) at 40–50 °C where the hydrophobic core material is also dispersed/dissolved. Stabilizers are usually added to the mixture to keep the individuality of the final particles.
How do dendrimers work?
Dendrimers are generally prepared using either a divergent method or a convergent one [38]. The core molecule reacts with monomer molecules containing one reactive and two dormant groups, giving the first-generation dendrimer. Then, the new periphery of the molecule is activated for reactions with more monomers.
