The possibility to detect and analyze single or few biological molecules is very important for understanding interactions reaction mechanisms. Ideally, the should be confined a nanoscale volume so that observation time by optical methods can extended. However, it has proven difficult develop reliable, non-invasive trapping techniques biomolecules under physiological conditions. Here we present platform long-term tether-free (solution phase) of proteins without exposing them any field...
Solid state nanopores have emerged as an important electrical label-free single-molecule detection platform. While much effort has been spent on analyzing the current trace to determine size, shape and charge of translocating species, a less studied aspect is number events how this relates analyte concentration. In work we systematically investigate event frequency depends voltage applied across pore show that dependence can be utilized target Importantly, method does not require any...
In nanobiotechnology, the importance of controlling interactions between biological molecules and surfaces is paramount. recent years, many devices based on nanostructured silicon materials have been presented, such as nanopores nanochannels. However, there still a clear lack simple, reliable, efficient protocols for preventing biomolecule adsorption in structures. this work, we show simple method passivation or selective biofunctionalization silica, without need polymerization reactions...
Mercury is a highly toxic heavy metal, and improved removal processes are required in range of industrial applications to limit the environmental impacts. At present, no viable methods exist commercially for mercury aqueous solutions at high acidic conditions, such as concentrated sulfuric acid. Herein, we show that electrochemical based on alloy formation platinum, forming PtHg4, can be used remove from Thin platinum film electrodes porous with supported more than 90% acid zinc smelter an...
New and improved methods to remove toxic mercury from contaminated waters waste streams are highly sought after. Recently, it was shown that electrochemical alloy formation of PtHg4 on a platinum surface with ions solution can be utilized for decontamination, several advantages over conventional techniques. Herein, we examine the process in more detail by concentration measurements using inductively coupled plasma mass spectrometry batch as well quartz crystal microbalance analysis both...
