| 20080206103 | Method For The Preparation Of Very Stable, Self-Assembled Monolayers On The Surface Of Gold Coated Microcantilevers For Application To Chemical Sensing - Methods for the preparation of a stable, self-assembled monolayer on the silicon surface or metallic coating of a microcantilever are disclosed. The methods produce a microcantilever suitable as a chemical sensor. In a microcantilever produced using one version of the method, a metallic coating is disposed on a side of the microcantilever, a bridging atom is bonded to the metallic coating, a first spacer group is bonded to the bridging atom, a second spacer group is bonded to the bridging atom, and a chemical recognition agent is bonded to the first spacer group. In another version of the method, a silicon surface of a microcantilever is hydrogen terminated, and a calixarene chemical recognition agent is carbon linked to the silicon surface using photochemical hydrosilylation. Among other things, the calixarene may be bonded to a crown ether for ion detection or bonded to a area for the recognition of explosives by hydrogen bonding to nitro groups. | 08-28-2008 |

| 20090133480 | Methods and device for fast creation of fluid interfaces and use of this device for determination of liquid-liquid and liquid-gas interfacial properties - The invention proposes new methods for fast fresh surface formation of a drop or bubble of a test fluid and a device to realize the new methods to determine the dynamic or equilibrium surface/interfacial tension (ST/IFT) of this liquid. The methods are implemented by means of a single device which is used both for dynamic and equilibrium measurements of the ST/IFT. Depending on the method, the determination of the ST/IFT can be performed either by Axisymmetric Drop Shape Analysis (ADSA) or Capillary Pressure Method (CPM) or both. In addition, with this device the Drop Volume Method and Stopped Jet Method can be realized, which has been modified and improved with the proposed invention in comparison with the known methods. The combination of several methods for creating a fresh surface and of two techniques for determining ST/IFT in a single device allows choosing the most suitable method for a given fluid system considering the system properties and desired time range. The proposed device consists of the following components: | 05-28-2009 |
