This article discusses three aspects of inner filter effect (IFE) in fluorescence spectroscopy.(i)
First, IFE as undesirable in fluorescence measurements: IFE results in non-linear …

Until very recently, handheld spectrometers were the domain of major analytical and security
instrument companies, with turnkey analyzers using spectroscopic techniques from X-ray …

Portable fluorescence sensors have been developed for biochemical detection, water
quality monitoring, biomedical sensing, and many other applications. With help of …

The field of point-of-care (POC) diagnostics offers the tantalizing possibility of providing
rapid diagnostic results in nonlaboratory settings. Here, we review progress in this research …

The traditional analytical biosensor instruments are relatively bulky, expensive, and not easy
to handle, thus their applications are largely limited in resource-limited settings. The recent …

Förster resonance energy transfer (FRET) occurs when the distance between a donor
fluorophore and an acceptor is within 10 nm, and its application often necessitates …

Smartphone has been widely integrated with sensors, such as test strips, sensor chips, and
hand-held detectors, for biochemical detections due to its portability and ubiquitous …

Considerable advances in point-of-care testing (POCT) devices stem from innovations in
cellphone (CP)-based technologies, paper-based assays (PBAs), lab-on-a-chip (LOC) …

Emerging smartphone-based point-of-care tests (POCTs) are cost-effective, precise, and
easy to implement in resource-limited areas. Thus, they are considered a potential …

Low-cost point-of-care (POC) diagnostics play several critical roles in healthcare strategies,
particularly for detection, therapy, economy, health management, and surveillance. Any user …
