Herein, we present the large-scale fabrication of multiplexed three-electrode sensors used in a point-of-care device platform that couples a magnetic bead-based immunoassay strategy with amperometric detection for rapid and highly sensitive analysis. The m ...

A combination of an immuno-affinity enrichment strategy and sensitive amperometric read-out was implemented in a point-of-care platform intended for bacterial infection analysis. Bacterial cells, selectively captured and enriched from complex matrices thro ...

A noninvasive electrochemical melanoma detection approach based on using adhesive tapes for collecting and fixing cells from a suspicious skin area and transferring the cells into a scanning electrochemical microscope (SECM) is presented. The adhesive laye ...

Matrix-assisted laser desorption/ionisation (MALDI) time-of-flight (TOF) mass spectrometry is an important analytical tool in chemistry and biology. Bearing the advantages of easy-to-use, fast measurements and relatively simple data interpretation, MALDI-T ...

A method for bacteria detection and the assessment of the antimicrobial susceptibility profile uses a bacterial viability assay based on combining a highly efficient affinity bacteria enrichment/ separation with an electrochemical redox interrogation measu ...

Matrix-assisted laser desorption ionization time-of-flight mass spectrometry is used to detect intact whole exosomes, yielding exosomal fingerprints within minutes. This rapid exosome detection approach is proposed as a potential tool for cancer studies. M ...

Inkjet printing of electrochemical sensors using a highly loaded mildly edge‐oxidized graphene nanosheet (EOGN) ink is presented. An ink with 30 mg/mL EOGNs is formulated in a mixture of N‐methyl pyrrolidone and propylene glycol with only 30 min of sonicat ...

Identifying multitarget impurities on contact lenses is challenging because traditional methods such as polymerase chain reaction cannot be used on the unknown target. Other sampling methods often require expensive antibodies or dyes. Therefore, this resea ...

Bloodstream infections rank among the most serious causes of morbidity and mortality in hospitalized patients, partly due to the long period (up to one week) required for clinical diagnosis. In this work, we have developed a sensitive method to quickly and ...

The present invention describes an adhesive tape stripping transfer method for quick and non-invasive diagnosis of skin diseases by MALDI-TOF mass spectrometry analysis. Cells from the epidermis layer of a suspicious skin area of a patient are collected us ...

Macromolecular mass fingerprinting using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry is a quick tool for biochemical analysis. In combination with algorithms for automated data analysis and interpretation, it has wide appli ...

Skin problems are often overlooked due to a lack of robust and patient-friendly monitoring tools. Herein, we report a rapid, noninvasive, and high-throughput analytical chemical methodology, aiming at real-time monitoring of skin conditions and early detec ...

A target plate for enhanced matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) analysis of intact biological entities. The target plate comprises an electrically conductive substrate (1) covered at least partially with immobilised pho ...

Titanium dioxide-modified target plates were developed to enhance intact bacteria analysis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The plates were designed to photocatalytically destroy the bacterial envelope struct ...
