The interface of biology and inorganic materials represents one of the fastest growing and most promising areas of nanotechnology. The fifth issue of JACS Select contains 22 Communications and Articles from 2008 and early 2009 that illustrate the breadth and creative energy of this young field. Although the use of colloidal particles of metals and semiconductors as pigments dates back many cent...

The optical properties of various nanostructures have been widely adopted for biological detection, from DNA sequencing to nano-scale single molecule biological function measurements. In particular, by employing localized surface plasmon resonance (LSPR), we can expect distinguished sensing performance with high sensitivity and resolution. This indicates that nano-scale detections can be realiz...

radically different computing concepts that leverage the physics of biological materials. For example, selforganization, self-repair, and self-reproduction are commonly found in biological systems but are difficult to achieve with conventional computing systems. New computing paradigms, such as cellular automata, neural networks, and evolutionary computing, may provide clues to utilize the comp...

Surface-enhanced Raman scattering (SERS) has demonstrated single-molecule sensitivity and is becoming intensively investigated due to its significant potential in chemical and biomedical applications. SERS sensing is highly dependent on the substrate, where excitation of the localized surface plasmons (LSPs) enhances the Raman scattering signals of proximate analyte molecules. This paper review...

In order to satisfy the accelerating nanotechnology of high-tech precision manufacturing, it is essential to develop the efficient integration of amplifying device producing very fine resolution. This paper proposes such a development using topological optimal synthesis to design a monolithic mechanical amplifying lever actuated by a PZT in single-axis nano-positioning stage. This one-piece com...

The history from bio-imaging to live single-cell mass spectrometry (MS) is herein reviewed. The limitation of the current bio-imaging method is probing only known molecules, and a method for finding new molecules is needed for cells which, however, show individual behaviors even in the same incubation dish. Single-cell MALDI-TOF/MS has been developed, but it can detect only molecules that can b...

Until recently, discoloration of the denim garment has been carried out through various methods including mechanical, chemical, physical and enzymatic treatments. In this study, the nano clay was co-applied in bio stone washing of denim with cellulase to obtain denim garment with a new look and clear effluent. Acid and neutral cellulases along with nano clay were applied on the dyed denim fabri...

Functionalize nano-architecture CaO/Ag-chitosan bio-nanoparticles were prepared by the acetic acid sol-gel process and loaded into chitosan nanocomposite. The so bioactive nano-CaO/Ag-chitosan nanocomposite was characterized using XRD, TEM, FE-SEM, optical, antimicrobial activity evaluated. antibacterial evaluations implied that chitosan, nano-CaO, are exhibited subtle activities against both G...
