They can be designed to specifically target cancer biomarkers, allowing for highly sensitive and accurate detection of cancer cells or molecules associated with cancer. Gene therapy: Nanocarriers, such as lipid nanoparticles or polymer nanoparticles, can deliver therapeutic genes to cancer cells. This approach aims to modify the genetic makeup ...
In polymer chemistry, in situ polymerization is a preparation method that occurs "in the polymerization mixture" and is used to develop polymer nanocomposites from nanoparticles. There are numerous unstable oligomers ( molecules ) which must be synthesized in situ (i.e. in the reaction mixture but cannot be isolated on their own) for use in ...
Polymer-drug conjugates are drug molecules held in polymer molecules, which act as the delivery system for the drug. Polymer drugs have passed multidrug resistance (MDR) testing and hence may become a viable treatment for endocrine-related cancers. A cocktail of pendant drugs could be delivered by water-soluble polymer platforms.
It can be directed to the location of cancer cells with sustained release behavior. Studies have also been done on gold nanoparticle responses to local near-infrared (NIR) light as a stimuli for drug release. In one study, gold nanoparticles functionalized with double-stranded DNA encapsulated with drug molecules, were irradiated with NIR light.
A Pilot Study of AuroLase™ Therapy (gold nano shells) in refractory and/or recurrent tumors of the head and neck was completed in 2009 [a] and two trials are currently using AuroLase™ therapy for the treatment of primary/metastatic lung cancer [b] and for prostate cancer. [c] Other gold nanoparticles on the market are mostly for synthesis ...
Researchers at Harvard and MIT, however, have been able to attach special RNA strands, measuring nearly 10 nm in diameter, to nanoparticles, filling them with a chemotherapy drug. These RNA strands are attracted to cancer cells. When the nanoparticle encounters a cancer cell, it adheres to it, and releases the drug into the cancer cell. [93]
Polymer nanoscience is the study and application of nanoscience to polymer-nanoparticle matrices, where nanoparticles are those with at least one dimension of less than 100 nm. The transition from micro- to nano-particles lead to change in its physical as well as chemical properties.
The homogenous polymer solution in the first step is thermodynamically unstable and tends to separate into polymer-rich and polymer-lean phases under appropriate temperature. Eventually after solvent removal, the polymer-rich phase solidifies to form the matrix and the polymer-lean phase develops into pores.
