Designing ultra-sensitive biosensors for early personalised diagnostics
Personalised medicine is one of the new developments that is deemed to revolutionise health care. A key component is the detection of biomarkers, proteins in blood or saliva, for example, whose presence or abnormal concentration is caused by a disease.
Pietro Gucciardi – Working towards a single-molecule biosensor
Until now, few biosensors have had the required sensitivity to detect single molecules. A novel approach for improved biosensor sensitivity has opened new avenues for developing new kinds of biosensors.
The Artificial Finger
Now European researchers of the projects NanoBioTact and NanoBioTouch delve deep into the mysteries of touch and have developed the first sensitive artificial finger .
A touchy feely artificial finger
An artificial finger could benefit patients with a missing finger in many ways. The most obvious, would be to add sensory feedback to their prosthesis . In addition, remote surgery could also benefit from a well-functioning artificial finger.
Gold nanoparticles enhance cancer diagnostics
Gold nanoparticles ( AuNPs ) present the many advantages of displaying relative biocompatibility, high light absorption and strong optical scattering properties. They are therefore good candidates to be used as probes for cancer imaging .
Artificial Noses as Diseases Busters
Artificial noses have, until now, been used to detect diseases such as urinary tract infection, Helicobacter pylori, tuberculosis, ear, nose and throat conditions and even lung cancer.
Nano Nose Smells Cancer
Chances of survival of prostate cancer depend strongly on the stage at which the disease is diagnosed. Now scientists have developed new methods relying on an electronic nose and optoacoustics to improve the diagnosis techniques and avoid fatal treatment delays.
Uncertainties surrounding nanoparticles aimed for medical use
Researchers are trying to find out more about the relationship between different NPs’ shapes, sizes and surface chemistries and how they behave in the human body.
