Synthesis and antibacterial activities of silver nanoparticle
No full textThis thesis is submitted in partial fulfilment of the requirements for the degree of Bachelor of Science in Microbiology, 2019.Catalogued from PDF version of thesis.Includes bibliographical references (page 43-45).Antibiotic resistance is on the rise for the last few decades. As commercial antibiotics are failing to combat microbes, alternative methods are being investigated. The properties of silver as disinfectant have been known for years. Synthesizing and using silver nanoparticles to inhibit the growth of drug-resistant bacteria can be the solution to combat this alarming problem. Here, silver nanoparticles were synthesized using 5 different methods. The synthesized particles were analyzed by UV spectrometry, Scanning Electron Microscopy and DLS Spectroscopy. AgNPs obtained from the first and fifth method of synthesis were most stable and uniform in size. Silver nanoparticle was found to have antimicrobial activities but that was not so significant.Lutful AlamB. Microbiolog

People with such issues have to face several hardships throughout their lifetime. Even though it is not a disease, but many of us still unable to understand that an autistic person is as normal as us with just different way of communication. In Bangladesh, almost 10% of the total population have disabilities. It is high time to realize that without the contribution and participation of a large portion of our population, we cannot help them to lead towards a good life.
The idea of an institute is to develop more interaction among teachers, parents and children with disabilities. The academy will not only provide proper education to the special children but also encouraging general people to know how autistic people deal with regular activities. This project will bring the opportunity to produce more facilities to the childrenwith disabilities and help them to participate socially.Salima Sharmin KhanB. Architectur
