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 ...
Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
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.
The microrobots proved effective in tests with mice. In the two studies, "Fluorescent dye or cell membrane–coated nanoparticle functionalized algae motors were further embedded inside a pH-sensitive capsule" and "antibiotic-loaded neutrophil membrane-coated polymeric nanoparticles [were attached] to natural microalgae".

Polymer-protein hybrids are a class of nanostructure composed of protein-polymer conjugates (i.e. complexes composed of one protein attached to one or more polymer chains). [1] [2] The protein component generally gives the advantages of biocompatibility and biodegradability, as many proteins are produced naturally by the body and are therefore well tolerated and metabolized. [3]
Another cancer related application, though still in mice probing stage, is the use of peptide-coated nanoparticles as activity-based sensors to detect lung cancer. The two main advantages of the use of nanoparticles to detect diseases is that it allows early stage detection, as it can detect tumors the size in the order of millimeters.
Some types of cancer cells will take up more of the particles than healthy cells will, giving researchers hope that MCM-41 will one day be used to treat certain types of cancer. [ 3 ] [ 19 ] [ 20 ] Ordered mesoporous silica (e.g. SBA-15, [ 21 ] TUD-1, [ 22 ] HMM-33, [ 1 ] and FSM-16 [ 23 ] ) also show potential to boost the in vitro and in vivo ...
