The sensing behavior of a MoS2-functionalized paper sensor towards dopamine was explored through a combinatorial approach of theoretical analysis, subsequent experimental validation, and machine-learning-driven predictive modeling of the measured electrochemical outputs. The suitability of the chosen 2D material for efficient detection of dopamine...

The present study employs density functional theory-based first principle calculation to investigate the electron transport properties of polyaniline following exposure to acidic and alkaline pH. In-situ deposited polyaniline-based paper device maintains emeraldine salt form while it is exposed to acidic pH and converts to emeraldine base when it i...

The extent of susceptibility towards miltefosine (Mil), amphotericin B (AmpB), and paromomycin (Paro) was measured among 19 clinical isolates of Leishmania donovani (LD). Thirteen of these clinical isolates were reported to exhibit low susceptibility towards sodium stibogluconate (SSG-R), while six of them were highly susceptible (SSG-S). The degre...

A novel yet simple electrochemical immunosensor for specific and reliable detection of endometriosis is developed. Alpha-1-B glycoprotein (A1BG) exhibits higher specificity and sensitivity compared to earlier reported endometriosis serum markers. It holds promise towards clinically significant diagnosis of endometriosis. The sensing device, fabrica...

Chronic obstructive pulmonary disease (COPD) and asthma are the two most common obstructive lung diseases which affects millions worldwide and impose an enormous burden on global healthcare. The overlapping features shared by these two diseases often make differential diagnosis difficult to achieve, leading to misdiagnosis of these patients. Both a...

A miniaturized paper-based disposable pH sensor has been developed for the measurement of urine pH. The proposed sensor requires $2~\mu \text{l}$ of analyte solution for rapid detection of the analyte pH with a response time of 3.07 sec and 36.04 sec for acidic and basic pH, respectively. The sensor is fabricated via in situ deposition of polyani...

Disposable low-cost sensors are essential for the detection of urea for environmental and healthcare applications. In this paper, we proposed a hand-drawn electrode paper chip sensor by utilising the enzyme modified cellulose fibre as a sensing and substrate material. Further modified cellulose fibres increase the impedance measurement stability an...
