标题:Multiple Electron Tunneling Paths Across Self-Assembled Monolayers Of Alkanethiols With Attached Ruthenium(Ii/iii) Redox Centers
摘要:Alkanethiol Monolayers With Pendant Redox Centers Are Deposited On Gold Electrolytes By Self-Assembly. The Monolayers Are Composed Of Both An Electroactive Thiol,Hs(Ch2)(N)C(O)Nhch(2)Pyru(Nh3)(5)(2+/3+),With 10-15 Methylene Groups,And A Diluent Thiol,Hs(Ch2)Mcooh,Also With 10-15 Methylene Groups. The Monolayers Are Classified As ''Matched'' (N = M),''Exposed'' (N = 15,M = 10-14),And ''Buried'' (N = 10,M = 11-15) According To The Relative Position Of The Redox Center. Cyclic Voltammograms In Aqueous Na2So4 Indicate That The Monolayers Are Close-Packed With The Redox Centers Residing In The Aqueous Phase In All But The Most Buried Cases. Measurements Of Electron Transfer Kinetics By Several Methods (Cyclic Voltammetry,Ac Impedance Spectroscopy,Chronoamperometry) Yield An Internally Consistent Set Of Kinetic Parameters,The Standard Rate Constant K Degrees,And The Reorganization Energy Lambda Of The Redox Centers. The Reorganization Energies Are In Good Agreement With The Theoretically Predicted Value Of 1.0 Ev For The Pyru(Nh3)(5) Redox Centers. Plots Of Ln(K Degrees) Vs M Are Linear In All Three Cases. The Slopes Of The Linear Regression Fit Provide Tunneling Parameters (Beta,Where K Degrees Approximate To E(-Beta M)) Of 0.97 +/-0.03 (Matched Cases),0.83 +/-0.03 (Exposed Cases) And 0.16 +/-0.02 (Buried Cases) Per Methylene. This Pattern Of Beta'S Is Interpreted In Terms Of Electronic Coupling Between The Redox Center And The Electrode Via Both The Redox Thiol And The Proximate Diluent Thiols,With The Coupling Via The Diluent Thiols Dominating In The Exposed Cases.

摘要:A new seedless synthesis of anisotropic nanoscale gold nanoflower (AuNF) particles uses bidentate thiolate ligands to protect the nanoparticle surface and a combination of reagents (for example, ligand, ascorbic acid, and hydroxide) to synthesis AuNF with controlled size and anisotropic properties. Compared to prior art gold nanospheres, AuNF produced approximately a 15-fold improvement in a drug delivery assay.

标题 :Universal one-pot and up-scalable synthesis of SERS encoded nanoparticles

摘要:The universal one-pot and up-scalable synthesis of SERS encoded nanoparticles relies on the controlled co-absorption of mercaptoundecanoic acid (MUA) and the Raman code on the metallic surfaces of the nanoparticles. In contrast to most of the reported procedures which typically involve complex steps, the present method has demonstrated to be an easy and fast one-pot approach for the production of SERS-encoded nanoparticles. This versatile strategy allows for the SERS codification of particles with every molecule with affinity toward the metal surface, independently of its chemical nature, as exemplified here in the fabrication of 31 different encoded particles using the same standard procedure. In addition to the easiness of preparation, scalability to the liter regime, stability in aqueous solutions including PBS and chemical diversity, our SERS-encoded particles show considerably higher optical efficiency than those fabricated by using PEG or PVP polymers.

标题:Synthesis Of Enzyme-Polymer Conjugates, Having Enhanced Activity & Stability
发明人：Maceda-Johnson Nestor
权利人:MACEDA JOHNSON NESTOR
摘要:A process for site-specific immobilization of an enzyme on a polymer involving pairing of an enzyme and polymer to optimize cross-linking between the enzyme and the polymer while avoiding conformational or biochemical inhibition of enzyme activity. The process involves site specific interaction in a multiple phase synthesis within a buffered reaction medium and in an inert atmosphere. The reaction kinetics of the conjugation are modulated by chilling the reaction medium containing the enzyme and polymer to about the maximum solvent density of the reaction medium. The cross-linking of the enzyme and a polymer pair performed produces an enzymatically active, stable conjugate.

摘要:An economic, direct synthetic method for producing water soluble ZnS QDs that are ready for bioconjugation is provided. The method can produce aqueous ZnS QDs with emission wavelengths varying from 400 nm to 700 nm. Highly luminescent metal sulfide (MS) QDs are produced via an aqueous synthesis route. MS QDs are capped with thiol-containing charged molecules in a single step. The resultant MS QDs exhibit the distinctive excitonic photoluminescence desired of QDs and can be fabricated to avoid undesirable broadband emissions at higher wavelengths. The aqueous ZnS QDs are stable in biological fluids over a long period of time. In addition, non-toxic ZnS QDs have been produced with good photoluminescence properties.
