Nanoarchitectonics with Porphyrin Functionalized DNA

DNA is well-known as bearer of the genetic code. Since its structure elucidation nearly seven decades ago by Watson, Crick, Wilkins, and Franklin, much has been learned about its detailed structure, function, and genetic coding. The development of automated solid-phase synthesis, and with it the availability of synthetic DNA with any desired sequence in lengths of up to hundreds of bases in the...

DNA nanoarchitectonics: assembled DNA at interfaces.

DNA is a powerful biomaterial for creating rationally designed and functionally enhanced nanostructures. DNA nanoarchitectures positioned at substrate interfaces can offer unique advantages leading to improved surface properties relevant to biosensing, nanotechnology, materials science, and cell biology. This Perspective highlights the benefits and challenges of using assembled DNA as a nanosca...

Multidimensional microscopy on living cells

Introduction An ongoing trend in scientific research is the development of techniques that can address multiple components of a system at a single time. DNA microarray analysis provides a snap shot of the set of genes expressed within a cell at a given time [1]. Multidimensional protein identification technology is being developed to determine the contents of heterogenous samples of proteins [2...

Comparative Study on the Ni2+ Biosorption Capacity and Properties of Living and Dead Pseudomonas putida Cells

Microbial cells have been successfully used as biosorbents to remove heavy metals from wastewater. In some cases, dead cells appear to offer more advantages than living cells in the removal and recovery of heavy metal ions from industrial wastewater. Maintaining higher biosorption capability and understanding t...
