Highly Sensitive and Disposable DNA‐Based Electrochemical Biosensor for Detection of Daunorubicin
Herin, a flower‐like porous MnO2‐modified pencil graphite electrode (MnO2‐PGE) is developed for the electrochemical determination of the anticancer drug daunorubicin and its interaction with dsDNA. The developed electrochemical nanobiosensor has some advantages, such as easy‐to‐handle, cost‐effective, portable, less time‐consuming assay and disposable.

Synthetic oligonucleotides: AFM characterisation and electroanalytical studies [PDF]
One of the most important steps in designing more sensitive and stable DNA based biosensors is the immobilisation procedure of the nucleic acid probes on the transducer surface, while maintaining their conformational flexibility.

Analytical ultrasonics for evaluation of composite materials response. Part 2: Generation and detection [PDF]
To evaluate the response of composite materials, it is imperative that the input excitation as well as the observed output be well characterized. This characterization ideally should be in terms of displacements as a function of time with high spatial ...

Voltammetric Determination of Boron using Poly Xylenol Orange-Modified Pencil Graphite Electrode
ABSTRACTThis study describes a new voltammetric method for sensitive and accurate determination of boron using the poly xylenol orange-modified and oxidized pencil graphite electrode. The oxidation of tiron at +0.86 V in the boron–tiron complex formed in phosphate buffer solution at pH 8 was evaluated as a response.
