Description:: Raman spectroscopy is an analytical technique that utilizes inelastic scattering of light to obtain structural information of analyte molecules. The weak intrinsic process of Raman scattering, however, can be greatly enhanced when molecules are placed on or near a surface of noble metal with nanostructures. Discovered over 40 years, surface-enhanced...

Description:: Metal–Organic Frameworks (MOFs) is a class of material comprising organic linkers and inorganic, metal-ion-containing nodes, with diverse functionalities and wide-range of applications. Because of their porous nature and functional nodes and linkers, they are competent candidates for gas storage, separation, catalysis, and so on. Most MOFs, however, are intrinsically insulating,...

Description:: Electrochemical reactions on the nanoscale play a pivotal role in a variety of areas, including electrocatalysis, energy conversion and storage, corrosion prevention, plasmon driven chemistry, and so forth. An in-depth knowledge of how site-specific compositions and morphologies locally affect the electron transfer kinetics will greatly benefit the design of catalysts,...

Description:: SAMDI-MS (Self-Assembled Monolayers for MALDI-TOF Mass Spectrometry) couples the use of chemically-defined self-assembled monolayers of alkane thiolates on gold surfaces with MALDI-TOF mass spectrometry for rapid characterization of the surfaces. Reactions performed on the surfaces can be quantified directly by detection of the reaction substrates and products. This rapid detection...

Description:: Epigenetics is the study of chromatin-based events that regulate gene expression without the change of DNA sequence, including DNA methylation, histone modification and chromatin remodeling. Epigenetic regulators are encoded to modify chromatin in a highly regulated and dynamic manner. A growing number of studies have suggested the dysregulation of epigenetic...

Description:: More than half of proteins in humans are modified with carbohydrates in a process called glycosylation, yet this process remains poorly understood even though approximately 1% of the expressed human genome encodes biosynthetic machinery for glycosylation. Unlike genomics and proteomics where high throughput tools are now routinely used to generate...

Description:: ABSTRACT Genome Mining in Actinobacteria via a Hybrid-Omics Discovery Platform James Hudson Tryon Natural products isolated from Actinobacteria are a vital source of medicines, agrochemicals, and commodity chemicals. The traditional, activity-driven fractionation pipelines that provided access to many of these natural products have delivered diminishing returns in recent decades. However,...
