All forms of energy follow the law of conservation of energy, by which they can be neither
created nor destroyed. Light-to-heat conversion as a traditional yet constantly evolving …

The ever‐growing global threats to human life caused by the human acute respiratory virus
(RV) infections have cost billions of lives, created a significant economic burden, and …

Traditional diagnostic strategies for infectious disease detection require benchtop
instruments that are inappropriate for point-of-care testing (POCT). Emerging microfluidics, a …

Human-infecting pathogens that transmit through the air pose a significant threat to public
health. As a prominent instance, the severe acute respiratory syndrome coronavirus 2 …

The sensitive detection of viruses is key to preventing the spread of infectious diseases. In
this study, we develop a silica-encapsulated Au core-satellite (CS@ SiO 2) nanotag, which …

Metasurfaces have revolutionized optical biosensing and diagnostic assays due to their
sensitivity, compactness, and label-free operation. However, metasurface applications in …

Surface-enhanced Raman scattering (SERS)-based assays have been recently developed
to overcome the low detection sensitivity of severe acute respiratory syndrome coronavirus 2 …

Gold nanoparticles (AuNPs) have received great attention for various medical applications
due to their unique physicochemical properties. AuNPs with tunable optical properties in the …

As the turnaround time of diagnosis becomes important, there is an increasing demand for
rapid, point-of-care testing (POCT) based on polymerase chain reaction (PCR), the most …

Nucleic acid detection has been one of the most valued tools in point-of-care diagnostics
from life science, agriculture, food safety and environmental surveillance, because of its high …
