Abstract:

Modern progress in nanotechnology has introduced a group of opto-electronically active metal or polymeric nanoparticles with attractive molecular and photo-physical properties suitable for various applications such as clinical diagnostics and environmental analysis. The present research trends have centered on exploring the fundamental optical, electrical and mechanical properties of new materials to efficiently enhance the performance of micro/nano-systems. In this presentation, we will showcase a novel synergism between the synthesis of Gold/Polymeric nanomaterials and their unique optoelectronic properties for two specific applications: (1) detection and treatment of deadly disease such as cancers and (2) fast, low-cost and in-field detection of environmental/biological toxins. The first part of the presentation involves the synthesis of size and shape dependent new gold nanoconstructs appropriate for theranostic applications in cancer management. The study will illustrate how cancer specific gold nanoparticles can be fabricated to target biomarkers present on cancer cells and used as image-contrast agents for the early detection and treatment of cancer. The second part includes the development of new micro/nanodevices as sensors for the rapid, low-cost and in-field detection of toxic heavy metal ions which are responsible for environmental pollution. The details of functionalized nanoparticles to produce significantly amplified optical signals through a small device having manifold receptors for analyte recognition will be explained. The significant outcome of this study is expected to develop a new technology that would enable the efficient detection of tracer level metal components in environmental and biological samples that are sometimes difficult to detect through traditional techniques
