Fiber optic array biosensors.
Optical fiber arrays provide a powerful substrate for creating high-density sensing systems that can address a variety of biological problems. The fiber substrate can be used to create femtoliter wells that can be loaded with individual beads to create high-density arrays for multiplexed screening and analysis. In addition, living cells can be loaded into the arrays, and their individual respon...
متن کاملRecent advances in fiber-optic DNA biosensors
Fiber-optic DNA biosensors are a kind of analytic setups, which convert the Waston-Crick base pairs matching duplex or Hoogsteen’s triplex (T/A-T, C/G-C) formation into a readable analytical signals when functionalized singlestrands DNA (ssDNA) or double-strands DNA (dsDNA) of interest are immobilized on the surface of fiber-optic hybrids with target DNA or interacts with ligands. This review w...
متن کاملFiber-optic chemical sensors and biosensors.
This biannual review covers the time period from January 2002 to January 2004 and is written in continuation of previous reviews (A1, A2). An electronic search in SciFinder and MedLine resulted in 532 hits. Since the number of citations in this review is limited, a stringent selection had to be made. Priority was given to fiberoptic sensors (FOS) for defined chemical, environmental, and biochem...
متن کاملFiber-optic biosensors based on fluorescence energy transfer.
A new optical homogeneous biochemical method for the assay of glucose has been developed, based on fluorescence energy transfer between a glucose analog, dextran labeled with fluorescein isothiocyanate (FITC-dextran), and a glucose-receptor protein, Rhodamine-labeled Concanavalin A (Rh-ConA). When FITC-dextran binds to Rh-ConA in solution, and is light-activated, the FITC label transfers its ab...
متن کاملLabel-free, disposable fiber-optic biosensors for DNA hybridization detection.
A novel and highly sensitive fiber-optic DNA sensor based on a thin-core fiber modal interferometer (TCFMI) is demonstrated by using a layer-by-layer (LbL) self-assembly technology. Poly(ethylenimine) (PEI), poly(acrylic acid) (PAA) and single-stranded DNA (ssDNA) were used for the preparation of a polyelectrolyte multilayer film for DNA detection. The film thickness was measured through a surf...
