Recycling of Polymerase Chain Reaction (PCR) Kits

Francesco Stellacci, Weina Liu, Yong Zhu

Polymerase chain reaction (PCR) kits have been used as common diagnosing tools during the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, with daily worldwide usage in the millions. It is well known that at the beginn ...

Distinguishing dopamine and calcium responses using XNA-nanotube sensors for improved neurochemical sensing

Ardemis Anoush Boghossian, Melania Reggente, Alice Judith Gillen, Alessandra Antonucci, Daniel Eduardo Morales Garza

To date, the engineering of single-stranded DNA-SWCNT (DNA-SWCNT) optical biosensors have largely focused on creating sensors for new applications with little focus on optimising existing sensors for in vitro and in vivo conditions. Recent studies have sho ...

Detecting DNA and RNA and Differentiating Single-Nucleotide Variations via Field-Effect Transistors

Nako Nakatsuka, Yang Yang, Bowen Zhu

We detect short oligonucleotides and distinguish between sequences that differ by a single base, using label-free, electronic field-effect transistors (FETs). Our sensing platform utilizes ultrathin-film indium oxide FETs chemically functionalized with sin ...

Allele-specific gene editing prevents deafness in a model of dominant progressive hearing loss

Bernard Schneider, Paola Andrea Solanes Vega, Sofia Carmen Suzanne Spataro

Since most dominant human mutations are single nucleotide substitutions(1,2), we explored gene editing strategies to disrupt dominant mutations efficiently and selectively without affecting wild-type alleles. However, single nucleotide discrimination can b ...

Aptamer Recognition of Multiplexed Small-Molecule-Functionalized Substrates

Nako Nakatsuka

Aptamers are chemically synthesized oligonucleotides or peptides with molecular recognition capabilities. We investigated recognition of substrate-tethered small-molecule targets, using neurotransmitters as examples, and fluorescently labeled DNA aptamers. ...

Improvement of breast cancer diagnosis through microfluidics

Huu Tuan Nguyen

In breast cancer, 15-20% of cases are reported with overexpression of human epidermal growth factor receptor 2 (HER2) that causes rapid cancer progression and poor prognosis. Fortunately, HER2-targeted therapy using specific antibodies such as Trastuzumab ...

Microfluidic-assisted chromogenic in situ hybridization (MA-CISH) for fast and accurate breast cancer diagnosis

Martinus Gijs, Raphaël Etienne Jean Trouillon, Huu Tuan Nguyen, Léa Suzanne Bernier

Chromogenic in situ hybridization (CISH) is a common technique that is used for human epidermal growth factor receptor 2 (HER2) assessment in breast cancer diagnosis. CISH is based on the enzymatic amplification of DNA markers, generating a colorimetric im ...

Label-Free Electrochemical Detection of MicroRNA-122 in Real Samples by Graphene Modified Disposable Electrodes

Tugba Kilic

In the present work, an electrochemical nucleic acid biosensor has been designed for the purpose of detection of miR-122 in real samples, i.e cell lysates. The fabrication of the biosensor has been done first by immobilization of complemantary anti-miR-122 ...

Extra short incubation microfluidic assisted – fluorescence in situ hybridization (ESIMA-FISH)

Martinus Gijs, Raphaël Etienne Jean Trouillon, Huu Tuan Nguyen, Estelle Annick Cuttaz, Laurène Nathalie Dupont

Fluorescence in situ hybridization (FISH) is a powerful technique for evaluating the HER2 gene status in breast cancer specimen (1). However, most of FISH assays currently used in clinical laboratories are expensive and require long experimental time, up t ...

Impedance sensing of DNA immobilization and hybridization by microfabricated alumina nanopore membranes

Jürgen Brugger, Philippe Renaud, Songmei Wu, Robert Meissner, Mojtaba Taghipoor

In this work we demonstrate microfabricated thin alumina nanopore membranes as a platform for impedance sensing of DNA immobilization and hybridization. We develop a wafer-scale fabrication of free-standing alumina nanopore membranes with well controlled t ...
