Opioids are widely used as therapeutic agents against moderate to severe acute and chronic pain. Still, these classes of analgesic drugs have many potential limitations as they induce analgesic tolerance, addiction and numerous behavioural adverse effects that often result in patient non-compliance....

An ethnomedicinal survey conducted in two sub-districts (upazillas) each of three districts of Bangladesh revealed that there is both inter- and intra-district variation between the choices of medicinal plants selected by folk medicinal healers (kavirajes) to treat any specific ailment. The variatio...

This paper presents a highly sensitive plasmonic refractive index (RI) sensor on a dual-core photonic crystal fiber (PCF). The performance of the RI sensor is weighed in terms of amplitude sensitivity, wavelength sensitivity, wavelength resolution, and linearity of the resonance wavelength. Numerica...

In this paper, two exclusive surface plasmon resonance (SPR) biosensors are proposed numerically utilizing the newly emerged transition metal dichalcogenides (e.g. PtSe2) composed with 2D materials (e.g. Graphene, MoS2 and WS2) onto the traditional SPR biosensors. The performance of the sensors is i...

Cancer is a chronic disease, and it can be lethal due to limited therapeutic options. The conventional treatment options for cancer have numerous challenges, such as a low blood circulation time as well as poor solubility of anticancer drugs. Therapeutic cancer vaccines emerged to try to improve ant...

Most surface plasmon resonance (SPR) based photonic crystal fiber (PCF) sensors have been designed to detect the analyte refractive index (RI) ranging from 1.33 to 1.41. In this paper, we propose a new approach to extend the detection range of the sensor, and it can be fabricated with the existing f...
