Solving the riddle of the bright mismatches: hybridization in oligonucleotide arrays [PDF]
HDONA technology is predicated on two ideas. First, the differential between high-affinity (perfect match, PM) and lower-affinity (mismatch, MM) probes is used to minimize cross-hybridization. Second, several short probes along the transcript are combined, introducing redundancy.

Single-molecule DNA Bases Discrimination in Oligonucleotides by Controllable Trapping in Plasmonic Nanoholes [PDF]
Surface-enhanced Raman spectroscopy (SERS) sensing of DNA sequences by plasmonic nanopores could pave a way to new generation single-molecule sequencing platforms. The SERS discrimination of single DNA bases depends critically on the time that a DNA strand resides within the plasmonic hot spot.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

G-spots cause incorrect expression measurement in Affymetrix microarrays [PDF]
Background High Density Oligonucleotide arrays (HDONAs), such as the Affymetrix HG-U133A GeneChip, use sets of probes chosen to match specified genes, with the expectation that if a particular gene is highly expressed then all the probes in ...

DNA detection by THz pumping [PDF]
Our results demonstrate a new method for label-free, real-time oligonucleotide characterisation by their self-resonant modes, which are unique to their conformation and sequence. We anticipate that our assay will be used as a starting point for a more detailed investigation of the aforementioned mechanism, which can be used as a basis for ...

Au-Ag template stripped pattern for scanning probe investigations of DNA arrays produced by Dip Pen Nanolithography [PDF]
We report on DNA arrays produced by Dip Pen Nanolithography (DPN) on a novel Au-Ag micro patterned template stripped surface. DNA arrays have been investigated by atomic force microscopy (AFM) and scanning tunnelling microscopy (STM) showing that the patterned template stripped substrate enables easy retrieval of the DPN-functionalized zone with a ...

Structured Light Projection Using Image Guide Fibers for In Situ Photo‐biofabrication
Light‐based biofabrication is typically performed with single wavelength light sources and within benchtop devices. This work demonstrates FaSt‐Light (Fiber‐assisted Structured Light) as a new approach to achieve multiwavelength image projection using flexible image guide fibers, which enables a variety of applications for in situ biofabrication ...

Systems Biology and the Development of Vaccines and Drugs for Malaria Treatments [PDF]
The sequencing race has ended and the functional race has already begun. Microarray technology enables simultaneous gene expression analysis of thousands of genes, enabling a snapshot of an organisms’ transcriptome at an unprecedented resolution.
