Gold nanoparticles (AuNPs) are relatively inert in the biological environment and have a number of physical properties that are suitable for several biomedical applications. Gold nanoparticles are the subject of intense studies due to the exceptional photo-optical properties combined with the biocompatibility and have proved to be a powerful tool in various nanomedical applications. The present review aims to summarize recent developments of AuNPs in biomedicine and diagnostics and discuss future prospects. Relevant theory and examples of the use of AuNPs in these applications have been cited and discussed to create a thorough understanding of the developments in this field. We further provided conclusions of present challenges and future perspectives of AuNPs for fundamental investigations and practical biomedical applications.</p> Muhammad Naeem Iqbal Copyright (c) 2019 PSM Mon, 30 Sep 2019 00:00:00 +0000 Isolation and Identification of Bacteria from the Rhizoplane of Rice <p>This study was conducted to characterize bacterial diversity in the rhizoplane of rice. Soil samples were collected in sterile Petri plates from the rhizoplane of different rice varieties grown in the Net house. Samples were analyzed for their bacterial content following colony morphology, microscopic and biochemical characters. Bacterial density recorded was in the range of 3.51 x 10<sup>4 </sup>- 2.63 x 10<sup>6</sup> organisms per gram of soil. The isolated microbes were represented by a mixed population of five species (<em>Bacillus</em> sp., <em>Staphylococcus</em> sp., <em>Streptococcus</em> sp., <em>Pseudomonas</em> sp., and <em>Escherichia coli</em>). This study revealed that the bacterial population in the rhizoplane of rice varies significantly which may have an impact on the plant roots for their tolerance to stress.</p> Saadit Rasool, Rubina Arshad, Faiza Iqbal, Iqra Iqbal Copyright (c) 2019 PSM Mon, 30 Sep 2019 00:00:00 +0000 Can Nanotechnology Improve Detection of the Seed-borne Pathogens through PCR? <p>Pathogens carried on or in seeds which scientifically called seed-borne may cause heavy yield losses. The failure to adequately identify and detect plant pathogens using conventional morphological techniques has led to the development of nucleic acid-based molecular approaches. Immuno-diagnostic tools can also be successfully employed for differential diagnosis, disease surveillance of seed-borne pathogens. The commonly used seed health tests in laboratories around the world lack specificity, sensitivity, speed, simplicity, cost-effectiveness, and reliability. PCR has many beneficial characteristics that make it highly applicable for detecting pathogens from seeds. In the PCR diagnosis study, the development of DNA extraction is one of the most important steps. The nanotechnology approaches using AgNPs and FeNPs in the DNA extraction method help to enhance the quantity and purity of the DNA template for successful PCR assay, resulting in improved detection of seed-borne plant pathogens.</p> Muhammad Naeem Iqbal, Asfa Ashraf, Azara Iqbal Copyright (c) 2019 PSM Mon, 30 Sep 2019 00:00:00 +0000
