Surface-enhanced raman nanobiosensor Assignees: Northwestern
University Abstract: The present invention relates to biosensors, in particular to
surface-enhanced Raman biosensors for detection of in vivo and ex vivo analytes. In
particular, the present invention provides compositions and methods for the in vivo
detection of analytes such as glucose. Claims: 1. A biosensor, comprising:a) a substrate;
andb) a plurality of nanobiosensors adherent to said substrate, comprising: a plurality of
nanospheres; a metal film over said nanospheres; and a self-assembled partition layer
formed on the surface of said metal film over said nanospheres comprising at least two
compounds, wherein said nanobiosensors are configured for the quantitative detection of an
analyte such that the spectrum of a surface-enhanced Raman scattering signal detected from
said plurality of nanobiosensors in the presence of said analyte is correlated with the
concentration of said analyte in a medium. [0012]The present invention additionally
provides a method for detection of an analyte, comprising providing a plurality of
nanobiosensors, the nanobiosensors configured for surface-enhanced Raman spectroscopy
detection of an analyte; and a device configured for the surface-enhanced Raman
spectroscopy detection of the analyte; and contacting the plurality of nanobiosensors with
a bodily fluid comprising the analyte; and detecting a surface-enhanced Raman signal from
the nanobiosensor using the device. In some embodiments, the level of the surface-enhanced
Raman signal is correlated with the concentration of the analyte in the bodily fluid. In
some embodiments, the detecting is in vivo. In some embodiments, the nanobiosensors are
implanted under the skin. In other embodiments, the nanobiosensors are implanted in an
eye.
Strani
filamenti nelle urine di soggetti apparentemente sani - Piante, uomini ed animali sono costantemente
esposti, nel loro ambiente, ad una vasta gamma di sostanze chimiche estranee agli
organismi naturali. Queste sostanze possono essere di origine naturale o umana. In genere
i composti lipofilici sono facilmente assorbiti attraverso la pelle, i polmoni o il tratto
gastrointestinale. Un’esposizione costante o anche intermittente a queste sostanze
lipofiliche potrebbe sfociare in un loro accumulo nell’organismo, a meno che non
siano presenti mezzi per l’eliminazione. Inoltre, le sostanze chimiche possono essere
espulse attraverso l’urina, la bile... >> SEGUE >>
Scie chimiche su Radio Imago - Intervista
a Rosario Marcianò
Il 12
febbraio 2010, all'interno della rubrica "Storie di frontiera",
grazie alla squisita ospitalità dell'emittente Radio Imago (radio
in streaming) e del conduttore Cesare Dal Pont
(pilota), abbiamo affrontato in modo pacato ed esaustivo il tema spinoso delle chemtrails.
Un particolare ringraziamento va all'amico elixam (per il contatto) ed al direttore
artistico Attilio Torrone per
la scelta della musica. Buon ascolto!
