Dry eye disease is a multifactorial disorder of the eye and tear film with potential damage to
the ocular surface. Various treatment approaches for this disorder aim to alleviate disease …

Artificial intelligence (AI) and wearable sensors are gradually transforming healthcare
service delivery from the traditional hospital-centred model to the personal-portable-device …

There is a significant demand for improved design and performance of gas sensors today. A
fiber optic gas sensor based on light detection from a side-polished clad modified optical …

Taste, as one of the natural chemical sensations, has attracted worldwide attention due to
their great significance to organismal survival in the area of seeking advantages and …

This paper presents the evaluation of the influence of surface roughness on the performance
of a refractive index sensor based on a D-shaped optical fiber. In addition, the manufacturing …

We synthesized novel pyrido [2, 3-b] pyrazin based heterocyclic compounds (4–7) and their
chemical structures were ascertained by spectral techniques (NMR, FT-IR). Besides …

In recent years, optical biosensors widely applicable for medical applications, have received
much attention. In this paper, we propose a high-performance polarization-insensitive …

We report a side-polished sensor structure for mid-infrared (IR) fiber evanescent wave
spectroscopy, produced by means of a mechanical polishing process. By integrating a mid …

In this paper, we propose fast, highly sensitive, and wide-dynamic-range fiber-optic probe-
type biosensors to detect pH and glucose. The operation principle of the proposed …

Here, we designed and developed an organic field-effect transistor (OFET)-based gas
sensor by applying solvatochromic dye (Nile red, NR) with twisted intramolecular charge …
