Gold Nanoshells
Nuclear Medicine and Biomedical Imaging Research Article Gold nanoshells: A ray of hope in cancer diagnosis and treatment Shanbhag PP*, Iyer V and Shetty T Saraswathi Vidya Bhavans College of Pharmacy, University of Mumbai, India Abstract Ideal properties of gold nanoshell has resulted in making it a ray of hope in biomedical areas such as targeted drug delivery, cancer detection and treatment and in eliminating tumors without harming normal healthy cells. Gold nanoshells are spherical particles with diameter ranging from 10-200 nm consisting of a dielectric core that is covered by a thin metallic shell of gold. An important role of gold nanoparticle based agents is their multifunctional nature. This review focuses on physics, synthesis and biomedical applications of gold nanoshells due to their inert nature, non-cytotoxicity and biocompatibility. Introduction Advantages The discovery of nanoshell was made by Professor Naomi J. 1. Biocompatibility Halas and her team at Rice University in 2003 [1,2].

UNESCO – EOLSS In the relatively near term, nanomedicine can address many important medical problems by using nanoscale-structured materials and simple nanodevices that can be manufactured SAMPLEtoday, including the interaction CHAPTERS of nanostructured materials with biological systems. In the mid-term, biotechnology will make possible even more remarkable advances in molecular medicine and biobotics, including microbiological biorobots or engineered organisms. In the longer term, perhaps 10-20 years from today, the earliest molecular machine systems and nanorobots may join the medical armamentarium, finally giving physicians the most potent tools imaginable to conquer human disease, ill-health, and aging. -

Nonclassical Vibration Analysis of Piezoelectric Nanosensor Conveying Viscous Fluid
WSEAS TRANSACTIONS on APPLIED and THEORETICAL MECHANICS Sayyid H. Hashemi Kachapi Nonclassical vibration analysis of piezoelectric nanosensor conveying viscous fluid SAYYID H. HASHEMI KACHAPI Department of Mechanical Engineering Babol Noshirvani University of Technology Shariati Street, Babol, Mazandaran 47148-71167 [email protected], IRAN Abstract: - In this paper, the natural frequency, critical fluid velocity and stability analysis of piezoelectric biomedical nanosensor (PBMNS) based on cylindrical nanoshell conveying viscous fluid is investigated using the electro-elastic Gurtin–Murdoch surface/interface theory. This system subjected to nonlinear electrostatic field and viscoelastic medium including visco-pasternak and damping coefficients. Hamilton’s principle and the assumed mode method combined with Euler – Lagrange is used for the governing equations and boundary conditions. It is shown that fluid velocity due to motion of biomarkers has major unpredictable effects on natural frequency and critical fluid velocity of the system and one should precisely consider their effects.

The 2018 Edward Noble Kramer Distinguished Interdisciplinary
Edward Noble Kramer was born April 17, 1908 in Cambridge, Wisconsin but grew up in the small town of Oregon, Wisconsin, just south of Madison, where his parents ran a printing business and published the The 2018 Edward Noble Kramer weekly newspaper, the Oregon Observer. He received his BS and MS degrees in chemistry from Distinguished Interdisciplinary Lecture the University of Wisconsin- Madison and after one year as instructor in chemistry at the University of Wisconsin- Extension at Milwaukee, returned to Madison and completed his PhD in chemistry in Professor Naomi J. Halas 1933 at the age of 25. At UW-Madison he was coxswain of the freshman crew and a member of the Department of Electrical and Computer marching band. He was hired by the DuPont Engineering Company at a time that DuPont had started to Rice University develop a new business to manufacture titanium dioxide white pigment. Over the span of his 40 year career at DuPont Dr. Kramer was intimately involved in the From Faraday to tomorrow: the Growing chemistry, chemical process engineering, physics and materials science of producing titanium dioxide nanoparticles of optimum size, crystal structure and surface Importance and Impact of Metallic characteristics to be effective paint additives. He had a major role in development of the chloride process for producing the rutile form of titanium dioxide, an exceptionally efficient Nanoparticles and controllable process used to produce almost all commercial titanium dioxide. When he retired in 1973 Dr. Kramer was in charge of all technical aspects of the Pigments Department of the DuPont Company. Tuesday, September 18, 2018 Since Dr.
