Copper phthalocyanine (CuPc):

It is also known as Phthalocyanine Blue BN, Monastral blue and phthalo blue. It is a semiconductor and is similar to the light harvesting part of the chlorophyll molecule. Read more…

Tiny device to capture, release and study cancer cells

Researchers have developed a device that captures/preserves and releases cancer cells circulating in the bloodstream.

This device has been developed by scientists from RIKEN Advanced Science Institute in Japan in collaboration with University of California Los Angeles and has been mentioned in the paper published online in the journal Advanced Materials.

This new device is a nanoscale Velcro-like device that can help not only in non-invasive diagnosis of cancer but also to study the mechanism involved in the spread of cancer in the body. With the help of this device doctors would be able to detect the cancer cells before their stay in the other organs. Moreover, the tumor cells would remain alive on the device, so the researchers would easily study them.

Blood passes through the device as a filter and the tumor cells adhere to the small molecules and separate them with 40%-70% of efficiency. Temperature at 37 degrees Celsius helps scientists to keep the tumor cells in tiny temperature-responsive polymer brushes or the temperature cooled to 4 degrees Celsius helps them to release and examine the cells.

Researchers wrote, “A platform for capture and release of circulating tumor cells is demonstrated by utilizing polymer grafted silicon nanowires. In this platform, integration of ligand-receptor recognition, nanostructure amplification, and thermal responsive polymers enables a highly efficient and selective capture of cancer cells. Subsequently, these captured cells are released upon a physical stimulation with outstanding cell viability.” Read more…

Novel technology to detect cancer in early stages

Researchers have developed novel technology to detect the tumors in the body in early stages with the help of nanoparticles that would help to amplify the minute cancerous alarms.

This research has been published in the December 16^th issue of the journal Nature Biotechnology.

Cancer cells produce many of the proteins that could be used as biomarkers to detect the cancer in the body but the amount of these proteins is not up to the mark or they may get diluted in the body of the patients making it nearly impossible to detect them in early stages.

Formation of brain cells from simple cells of urine

Researchers have utilized the cells in human urine to make brain cells.

This research has been published online in the journal Nature Methods.

In this study, researchers have found that the human excreta could be powerfully used to study different diseases thereby help us in overcoming some of the problems of utilizing stem cells. Not only this but it can also help us one day to control neurodegenerative diseases.

Researchers in this study presented the clear-cut way to utilize the cells in the human urine to be converted into valuable neurons. Interestingly, researchers have not used the stem cells, which can result in the development of tumors upon transplantation; instead they used simple cells and converted them into neural progenitor cells, which are the originator of brain cells. These are precursor cells and can be easily used in different individuals than the current procedures.
