This study focuses on the use of gold nanoparticles with DNA-based signal amplification as a detection method for low concentrations of DNA biomarkers. Biotechnology is a rapidly evolving field with primarily medical applications. Early detection is a challenging process for some cancers and other diseases yet is so critical to successful treatment. Increasingly sensitive detection techniques a...

Conventional therapeutic agents have displayed significant shortcomings. For this reason, important achievements have effectively made in biotechnology for delivering the therapeutic agents to the site of action, and diminish side effects. Polymeric carriers, micelles, dendrimers, liposomes, solid lipid carriers, gold carriers, viral carriers, nanotubes and magnetic carriers incorporating cytot...

Plasmonic nanoparticles have been increasingly investigated for numerous applications in medicine, sensing, and catalysis. In particular, gold nanoparticles have been investigated for separations, sensing, drug/nucleic acid delivery, and bioimaging. In addition, silver nanoparticles demonstrate antibacterial activity, resulting in potential application in treatments against microbial infections...

Production of nanoparticles has been attractive by biological based fabrication as an alternative to physical and chemical approaches due to exceeding need to develop safe, reliable, clean and eco-friendly methods for the preparation of nanoparticle for pharmaceutical and biomedical applications. In the present study, biogenic tellurium nanoparticles (TeNPs) were successfully prepared using pot...

the most modern techniques in biotechnology owe their existence to the discovery of dna cloning and the genetic manipulation of organisms. however biotechnology is not new science in fact, many applications represent old practices with new methodologies. human have been used organisms for their benefit in many processes for several thousand years. therefore, one way of thinking about biotechnol...

a healthcare system has been the most important priority for all governments worldwide. biotechnology products have affected the promotion of health care over the last thirty years. during the last several decades, iran has achieved significant success in extending healthcare to the rural areas and in reducing the rates of infant mortality and increasing population growth. biomedical technology...
