Aluminum nanoparticles show promise as less toxic alternative to gold

Agents to control bleeding show promise.

Every year, thousands of patients develop deep vein thrombosis (DVT) and are at risk of pulmonary embolism after undergoing surgeries, particularly orthopedic procedures in the hips and legs. Although low-molecular-weight heparin is considered the standard therapy for DVT and other forms of venous thromboembolism, it is far from an ideal anticoagulant. Its drawbacks include the need for daily i...

Gold nanoparticles as cancer theranostic agents

The application of nanotechnology in medicine involves using nanomaterials to develop novel therapeutic and diagnostic modalities. Given the unique physiochemical and optical properties of gold nanoparticle (GNP) such as good biocompatibility, nontoxic nature, surface properties and comparative stability, it has been widely studied in medicine, especially as a cancer theranostic agent. Th...

USE OF TITANIUM AND TUNGSTEN AS AN ALTERNATIVE TO GOLD IN JEWELLERY MANUFACTURING

In this study the use titanium and tungsten as alternatives to the noble metals in the jewellery industry was investigated. The degradation of titanium and tungsten were compared to that of gold, used as reference. Alternate immersion tests were performed in 3.5% sodium chloride and artificial perspiration. The metals’ abrasion resistance with respect to textile fabrics was determined. ...

Gold Nanoparticles as Absolute Nanothermometers

Nanothermometry is a challenging field that can open the door to intriguing questions ranging from biology and medicine to material sciences. Gold nanorods are excellent candidates to act as nanoprobes because they are reasonably bright emitters upon excitation with a monochromatic source. Gold nanoparticles are commonly used in photothermal therapy as efficient transducers of electromagnetic r...
