Patent number: 9005890Abstract: Metal enhanced luminescence using alloy nanoparticles offers additional degrees of freedom for tuning their optical properties by altering atomic composition and atomic arrangement when compared to pure metal nanoparticles such as gold and silver. Surface plasmon resonance wavelengths of silver-copper nanoparticles were tuned in the visible and near infrared region by changing annealing temperature. Strong emission enhancement of luminophores at the vicinity of the Ag—Cu nanoparticles was shown when the SPR spectrum was tuned to produce maximum spectral overlap. As the SPR spectrum can be easily tailored, this platform can be effectively used to enhance luminescence of different luminophores.Type: GrantFiled: August 28, 2009Date of Patent: April 14, 2015Assignee: University of South FloridaInventors: Venkat R. Bhethanabotla, Sanchari Chowdhury

Patent number: 9005896Abstract: The present invention describes methods for amplifying a target nucleic acid wherein target nucleic acids hybridize to capture probe nucleic acids which are immobilized to a support via their 5? end. The hybridization product is further extended with a polymerase to form a double stranded nucleic acid. To this double stranded nucleic acid, a hairpin nucleic acid is ligated. This ligation product is further amplified and sequenced.Type: GrantFiled: August 31, 2011Date of Patent: April 14, 2015Assignee: Koninklijke Philips N.V.Inventors: Harma Feitsma, Marlieke Overdijk, Anja Van De Stople, Pieter Jan Van Der Zaag

Patent number: 9005897Abstract: We disclose a method comprising: (a) providing an embryonic stem (ES) cell; and (b) establishing a progenitor cell line from the embryonic stem cell; in which the progenitor cell line is selected based on its ability to self-renew. Preferably, the method selects against somatic cells based on their inability to self-renew. Preferably, the progenitor cell line is derived or established in the absence of co-culture, preferably in the absence of feeder cells, which preferably selects against embryonic stem cells. Optionally, the method comprises (d) deriving a differentiated cell from the progenitor cell line.Type: GrantFiled: March 7, 2013Date of Patent: April 14, 2015Assignee: Agency for Science, Technology and ResearchInventors: Sai Kiang Lim, Elias Lye
