Multifunctional polymeric nanoparticles with trimodal affinity for liver cancer therapy

Thu, 05/14/2020 - 09:51
Hepatocellular carcinoma (HCC) is is the most common type of primary liver cancer and one of the most aggressive and hyper-vascularized forms of cancer. Many current chemotherapeutics fail to achieve the effective therapeutic index in the solid tumours due to poor drug penetration, poor bioavailability, non-specificity and drug resistance - a challenging aspect in this field. In search of new modalities, researchers have developed multifunctional polymeric nanoparticles against HCC. These biocompatible multifunctional polymeric nanoparticles hold trimodal affinity towards targeting microtubules, tyrosine kinases, and high-sensitivity imaging system quantum dots.

Carbon nanotubes pave the way for human breath analysis of lung disease

Wed, 05/13/2020 - 11:42
Breath is one of the main sources of human health parameters that can be used for predicting the state of internal organs. Exhaled breath composition is very complex and the existence of disease marker molecules can be as low as one part per million. That means that using breath for health monitoring purposes requires highly sensitive tools with a recognition ability down to single molecules. Researchers developed a method for fast, on-site and still accurate breath analysis that does not need special preparation of breath samples. The method is based on an electronic nose platform that uses a set of single-walled carbon nanotube sensors deposited on flexible substrates and modified by different semiconducting organic molecules.

Nanotechnology-based approaches to testing for COVID-19 infections in high-risk individuals

Tue, 05/12/2020 - 10:32
In the absence of vaccines, many scientists argue that the best approach to control the spread of the Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) would be fast, cheap, reliable, and portable means of diagnosing COVID-19 infection. In particular, the identification of patients with the highest risk of COVID-19 mortality (i.e. those with co-morbidities such as cardiovascular disorders or massive alveolar damage and progressive respiratory failure) could significantly improve the capacity of healthcare providers to take early action and minimize the possibility of overwhelming care centers, which in turn would save many lives.
