Scientists develop biocompatible anti-burn nanofibers that act as ‘living bandages’

16.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

A group of NUST MISIS's young scientists has presented a new therapeutic material based on nanofibers made of polycaprolactone modified with a thin-film antibacterial composition and plasma components of human blood. Biodegradable bandages made from these fibers will accelerate the growth of tissue cells twice as quickly, contributing to the normal regeneration of damaged tissues, as well as preventing the formation of scars in cases of severe burns.

Claw-like nanowires filter bacteria from blood

13.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

A team of researchers from institutions across China has developed a new type of dialyser —one capable of capturing up to 97 percent of bacteria present in a blood sample. In their paper published in the journal Nature Communications, the group explains the origins of their device, how the filter was made and how well it worked during testing.

A synthetic cell that produces anti-cancer drugs within a tumor

13.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Technion-Israel Institute of Technology researchers have successfully treated a cancerous tumor using a "nano-factory" – a synthetic cell that produces anti-cancer proteins within the tumor tissue. The research, which was published in Advanced Healthcare Materials, combines synthetic biology, to artificially produce proteins, and targeted drug delivery, to direct the synthetic cell to abnormal tissues.

Using injectable self-assembled nanomaterials for sustained delivery of drugs

12.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Because they can be programmed to travel the body and selectively target cancer and other sites of disease, nanometer-scale vehicles called nanocarriers can deliver higher concentrations of drugs to bombard specific areas of the body while minimizing systemic side effects. Nanocarriers can also deliver drugs and diagnostic agents that are typically not soluble in water or blood as well as significantly decrease the effective dosage.

Cancer-fighting nanorobots programmed to seek and destroy tumors

In a major advancement in nanomedicine, Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences, have successfully programmed nanorobots to shrink tumors by cutting off their blood supply.

Active delivery of Cas9-sgRNA complex in the cell by using ultrasound-propelled nanomotors

09.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

In cancer research, the "Cas-9-sgRNA" complex is an effective genomic editing tool, but its delivery across the cell membrane to the target (tumor) genome has not yet been satisfactorily solved. American and Danish scientists have now developed an active nanomotor for the efficient transport, delivery, and release of this gene scissoring system. As detailed in their paper in the journal Angewandte Chemie, their nanovehicle is propelled towards its target by ultrasound.

First hybrid nanotech device mimicking blood-brain barrier

09.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Researchers at IIT-Istituto Italiano di Tecnologia fabricated an artificial device reproducing a 1:1 scale model of the blood-brain barrier (BBB), the anatomical and functional structure that protects the central nervous system from external toxins, but which also screens drugs when they are injected intravenously. The device, which is a combination of artificial and biological components, is fundamental for studying new therapeutic strategies to overcome blood-brain barrier and treat brain conditions such as tumors.

New, safe zinc oxide quantum dots

Nowadays, zinc oxide nanoparticles are among the most commonly used nanomaterials. They seem to be safe for humans, but there are still no standards for their toxicity, and despite investigations, the toxicological impact of ZnO nanomaterials remains ambiguous. Researchers from the Polish Academy of Sciences (IPC PAS) in Warsaw and the Warsaw University of Technology (PW) have recently developed a method for producing defect-free ZnO quantum dots with enduring physicochemical properties such as monodispersity, a relatively high quantum efficiency, record-long luminescence lifetimes and EPR silence under standard conditions. The tightly coordinated and impermeable organic shells that stabilize the surface make the new ZnO quantum dots resistant to both chemical and biological environments.

A biological approach to precision medicine targets endless number of diseases

01.02. 2018 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

The biological complexity of cancer and other diseases demands a more formidable arsenal of therapies than currently available. Most therapeutic approaches ignore the dynamic molecular network of genes, targeting instead only very few selected disease-related genes.
