The multifactorial nature of cancer still classifies the disease as one leading causes death worldwide. Modern medical sciences are following an interdisciplinary approach that has been fueled by nanoscale revolution past years. exploitation high-Z materials, in combination with ionizing or non-ionizing radiation, promises to overcome restrictions imaging and augment efficacy current therapeuti...

The rapid growth in the use of electronic equipments, combined with early obsolescence has contributed enormously to the generation of large quantity of electronic (e) waste. One such e-waste, the mobile phone printed circuit boards (PCBs) contain various precious metals which can be extracted by different hydrometallurgical routes. The present work deals with the recovery of gold using ammoniu...

Nanoparticles (NPs) of noble metals, namely gold and silver, remain promising anticancer agents capable of enhancing current surgery- and chemotherapeutic-based approaches in cancer treatment. Bimetallic AgAu composition can be used as a more effective agent due to the synergetic effect. Among the physicochemical parameters affecting gold and silver nanoparticle biological activity, a primary c...

For the development of surface-functionalized gold nanoparticles as cellular probes and delivery agents, we have synthesized hetero-bifunctional poly(ethylene glycol) (PEG, MW 1500) having a thiol group on one terminus and a reactive functional group on the other for use as a flexible spacer. Coumarin, a model fluorescent dye, was conjugated to one end of the PEG spacer and gold nanoparticles w...

Indonesia is a country rich in mines, such as gold, silver, petroleum, etc. Mining must be carried out by the government or private sector. Every mining company required to obtain permit regulated Government Regulation Number 4 of 2009 concerning Mineral conjunction with 23 2010 Implementation Mining. In fact, not all companies have license. There are so many operating illegally. One them gold ...

Gene transfer to plants and the production of transgenic plants with various purposes, such as improving the performance and quality, resistance to pests, diseases, etc., and of great importance are carried out Gene transfer to plants performs to evaluate the transient and permanent gene expression. Transient expression is quick, easy and simple and is not influenced by position effect compare ...
