Abstract:
A colorimetric-based DNA diagnostic system which includes a detector module, a processor and a memory is provided. The detector module is disposed to record an image of a DNA sample illuminated by a light source. The memory includes computer program code which along with the memory is configured, with the processor, to perform (a) sending a signal to adjust the temperature of the DNA sample to be within an approximate temperature range over which the color of the DNA sample changes, (b) sending a signal to the detector module to capture an image of the DNA sample at defined intervals within the approximate temperature range, (c) processing the captured images to extract color information, and (d) processing the extracted color information to objectively determine a melting temperature within the approximate temperature range at which the color of the DNA sample changes.

Abstract:
There is provided polymer-flavonoid conjugates. Flavonoid-grafted and flavonoid-terminated polymer conjugates are disclosed according to the invention. The linkage of flavonoids to the polymers has been achieved via thiol linkages. The inventive processes allow for making of the conjugates in high yield avoiding complex purification steps. The conjugates can be easily autoxidized to hydrogels with uses in many biomedical applications where a higher stability of the flavonoid is necessary. The hydrogels can be potentially used as viscosupplement, anti-adhesion film or dermal filler.
Abstract:
A method for determining an occurrence of a spike in one of a plurality of neural signals is provided, the spike relating to an action potential in the one of the plurality of neural signals. The method includes sampling the plurality of neural signals at a sampling frequency; extracting frequency features from each of the plurality of neural signals during sampling of the plurality of neural signals; and monitoring the extracted frequency features to determine characteristics of the one of the plurality of neural signals indicative of an occurrence of a spike.
Abstract:
The present invention relates to a method for synthesizing an optionally substituted furoic acid by dehydrating a biomass and oxidizing the optionally substituted furan derived from the dehydration reaction. Water extraction has been incorporated as a step between the dehydration and the oxidation in order to purify the intermediate optionally substituted furan before having it oxidized. Prior to this water extraction, the organic solvent used for dehydration may be separated by evaporation. The provision of the water extraction allows impurities to be separated from the intermediate optionally substituted furan.
Abstract:
The present invention relates to methods and compositions for detecting an interaction between a protein and a ligand, comprising: (i) binding at least one fluorescent molecular rotor to said ligand or protein; and (ii) detecting a change in fluorescence emitted by said fluorescent molecular rotor after contact of the bound fluorescent molecular rotor with the other of said ligand or protein, thereby detecting an interaction between the ligand and the protein, wherein the fluorescent molecular rotor comprises: a rotating ?-bond; an electron-donating moiety; an electron-accepting moiety; and a ?-conjugated linker.
Abstract:
Present invention relates to methods of preparing molybdenum oxide inks and molybdenum oxide films, and use of the molybdenum oxide films as hole-transporting layers in optoelectronic devices. The ink for forming a hybrid molybdenum (VI) oxide (MoO3) film on a substrate comprises an ammonium molybdate, at least one inorganic salt different from ammonium molybdate, and a solvent or a solvent mixture.
