(Phys.org) —A combined team of researchers from Spain and Australia has discovered what they claim is the first known instance of a biomaterial that can kill bacteria on contact based only its physical surface structure. In their paper published in Biophysical Journal, the team describes how they found that clanger cicadas have nanoscale sized pillars on their wings that trap and slowly kill bacteria by pulling their cells apart.
On April 26, 2012, 200 Boston-area students, MIT scientists and local community members came together to make cutting-edge cancer research come to life in the Bio Flash Mob. This event was organized for the Cambridge Science Festival by the Koch Institute for Integrative Cancer Research at MIT. Learn more at http://ki.mit.edu and http://www.facebook.com/kochinstitute.
About the Book: Many researchers and research groups around the globe are dealing with interdisciplinary problems and multidisciplinary groups; but especially those that deal everyday with biosensors have the feeling of not having enough personnel with the sufficient background to cover all topics. With this feeling in our minds, we decided to invite wonderful researchers from different parts to design this book, not as a conventional biosensor’s book, but as an interesting journey in the complex world of biosensors. A close look to some recent and key advances on the topic, but at the same time tips through novel mathematical modelling to improve our work, and last but not least, tricks to fool those undesired electrical disturbances that commonly messes our daily work can be found in these pages.
Feel free to navigate the book through its chapters, once in your hands you will feel eager to learn more about biosensors. It has been an experience to put all this together; but now, with the book ready, we can say that this trip has being a wonderful adventure. That is why want to thank all the authors for their great contributions, the Editorial and Irene for their constant input, and to you, the reader, for being part of this book.
About the Chapter (1)-Use of functonal metalic nanostructures in biosensors by Rükan Genç.
The number of diferent type of nanostructures is increasing and wide range of nanoscale materials of diferent sizes, shapes and compositons are now available . From those, mainly, nanomaterials can be divided into three main classes depending on the material they are made up of: i) inorganic nanopartcles where the core material is an inorganic element or mixture (e.g; gold, silver, TiO2, ZnO, CdS and so on), ii) organic sof nanomaterials which are formed of organic materials including lipids, peptdes, genetc material, and finally, iii) nanocomposites which are based on both organic and inorganic materials, for example, magnetosomes, metal coated carbon nanotubes and peptde amphiphiles. However, this chapter will only cover the state of the art associated to the advantages ofered by diferent types of inorganic nanomaterials and their composites. Collecton of literature on challenges and drawbacks, and real world applicatons of these kinds of nanomaterials in biosensor development, including current status and future prospects will also be served to the readers’ interest.
