Analyst Issue 21 now online!

The latest issue of Analyst is online with three cover articles for you to enjoy.

Outside front cover, Analyst, Issue 21, 2012

Chung et al., Analyst, 2012, 137, 4921

The very informative front cover comes from Yu-Chang Tyan and Tze-Wen Chung from the National Yunlin University of Science and Technology and Kaohsiung Medical University, respectively, and colleagues from Taiwan. In their study they proposed a new approach for the detection of proteins to assess the response of fibroblasts to a material surface. Biomaterials play an important role in regenerative medicine and drug delivery, therefore the interactions between biomaterial surfaces and cells are important to characterize cell proliferation, differentiation and regeneration of tissues.

Inside front cover, Analyst, Issue 21, 2012

Kaminskyj et al., Analyst, 2012, 137, 4934

We head to Canada for our inside front cover. Kathleen M. Gough and Susan G. W. Kaminskyj from the University of Manitoba and the University of Saskatchewan, together with colleagues have been studying the filamentous fungi Aspergillus. This fungi can can affect humans through their roles in biotechnology and recycling, and can also be responsible for disease.

What they have discovered is that Surface Enhanced Raman Scattering (SERS) can provide chemical information on materials that are in close contact with appropriate metal substrates, in this case nanopatterned gold surfaces and gold nanoparticles (AuNPs). They have created conditions for AuNP formation within and on the surface of Aspergillus nidulans hyphae in order to explore their potential for SERS analysis.

Back cover, Analyst, Issue 21, 2012

Zhang et al., Analyst, 2012, 137, 4917

On the back cover of this month’s issue we showcase the work contributed by Weidong He, and Xiao Lin at the Vanderbilt Institute of Nanoscale Science and Technology, and the Institute of Physics, Chinese Academy of Sciences who together with colleagues have studied the analytical expression of Coulombic interaction between a nanorod and a nanoparticle.
