Silver Nano particle for Antimicrobial Activity

Silver is a precious metal

Silver has long been cherished as an antique valuable metal. It has a wide variety of uses for domestic purposes. Fundamentally it was used for cooking purposes. Because it has the capacity to transfer heat very easily. Still, men use it for cooking as well as keeping something in a pot made of silver.Some properties make a good sense of using silver-

  • It is a metal of brilliant metallic luster
  • It has high thermal conductivity and electrical conductivity
  • Silver is itself a lightweight metal. So everyone can bear the accessories made of this metal.

Other Reasons for attracting silver as a worthful metal

  1. It has a major use for jewelry and people use it for same cases still.
  2. It has also the application for electronic machines.
  3. It is used for photography. The chemical substance silver halide made from silver plays a major role in photography. Although, digital photography does not use silver halide.

The approach of silver at the nanoscale as silver nanoparticles

Apart from the view of its various uses from ancient times to modern times, silver has a great value in nanoscience. Silver has attracted a very good approach in nanotechnology. Because silver nanoparticles have a biomedical application, particularly for treating diseases. Mainly silver nanomaterials have a great application for wound dressing as it kills microorganisms grow around the affected parts. That’s why it has a great antimicrobial activity.

Synthesis methods of silver nanoparticles-

There some ways to synthesize silver nanoparticles. such as chemical synthesis and biosynthesis.

Biosynthesis is certainly named as green synthesis. In recent times, green synthesis has gained greater benefits than chemical synthesis.

Why does chemist prefer green synthesis to synthesize silver nanoparticle?

  • It is easy to produce silver nanoparticles by reducing it with different plant extracts.
  • It does not produce any harmful chemicals during synthesis.
  • It is environmentally friendly.


About Md. Shafiul Islam

I have been working as an Assistant Professor since May 26, 2015.My research profile lies at the interface of biomaterial science, life sciences and engineering. I am particularly interested in the design of bionanocomposite materials for relevant clinical applications, e.g. in the context of fabricating and testing biocomposite materials to study the biocompatibility with human body to repair bone tissue. I joined as a lecturer at Noakahli Science and Technology University in May 26,2013. During my working as a Lecturer, I did research on waste water treatment. In connection to this, I applied nanotechnology to treat water as well as waste water. Prior to joining the Noakhali Science and Technology University , I joined as a Scientific Officer in Drug & Toxins Lab as well as Polymer Chemistry Lab at Bangladesh Council of Scientific & Industrial Research (BCSIR).Before doing scientific works, I did M.S. thesis work in the Institute of Polymer & Radiation Technology. I completed my undergraduate studies in Applied Chemistry & Chemical Engineering ( University of Dhaka, Bangladesh) and gained my M.S. in the same department, under the supervision of Professor Dr. Mohammed Mizanur Rahman (University of Dhaka, Bangladesh), where he investigated the effect of reinforcement of nano-materials into bio-polymer composite, morphology and the effect of bacteria in the bio-composite. . I achieved Dean's Award in recognition of my excellent academic and oerall performance in B.Sc. In Bangladesh,I was shortlisted for National Science & Technology (NST) Fellowship and was successful in securing funding from Ministry of Science & Technology, in collaboration with Professor Dr.Mohammed Mizanur Rahman, University of Dhaka, towards the manufacture of medical devices that are resistant to microbial colonization. I have authored 6 research papers and 1 conference paper (h-index: 2).
