  • Patent number: 9481905
    Abstract: A method of using Neutrilized DNA (N-DNA) as a surface probe for a high throughput detection platform is disclosed. FET and SPRi are used as high throughput detection platforms to demonstrate that the N-DNA surface probe produces good results and enhances detection sensitivity. The N-DNA modifies the charged oxygen ions (O?) on the phosphate backbone through methylation, ethylation, propylation, or alkylation, so that the backbone is not charged after this modification to increase the hybridization efficiency, sensitivity and to make the signal more clear.

  • Patent number: 7490948
    Abstract: The present invention is an improved book cover and removable reading light, the book cover having a central spine section having a longitudinal pocket therein and two outer covers each pivotally connected to opposite edges of the central spine section. An elongated reading light is removably mounted in the pocket of the central spine section, the reading light having a housing including a battery compartment for receiving batteries and a second compartment for receiving an extendable supporting arm for the reading light. The supporting arm and reading light are disposed for movement relative to the second compartment between an open position in which the supporting arm extends out of the second compartment and a closed position in which the supporting arm is disposed within the second compartment. In addition, the reading light is movably mounted relative to the supporting arm for directing light in different directions, as desired by the user.
