Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Since the isolation of graphene in 2004, there has been an exponentially growing number of
reports on layered two-dimensional (2D) materials for applications ranging from protective …

Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm
in length) and possibly even nanoplastics (< 1 μm) has recently raised health concerns. In …

The performance of light microscopes is limited by the stochastic nature of light, which exists
in discrete packets of energy known as photons. Randomness in the times that photons are …

All molecules consist of chemical bonds, and much can be learned from mapping the
spatiotemporal dynamics of these bonds. Since its invention a decade ago, stimulated …

Creating functional electrical circuits using individual or ensemble molecules, often termed
as “molecular-scale electronics”, not only meets the increasing technical demands of the …

High-speed measurement confronts the extreme speed limit when the signal becomes
comparable to the noise level. In the context of broadband mid-infrared spectroscopy, state …

Advancement in mid-infrared (MIR) technology has led to promising biomedical applications
of MIR spectroscopy, such as liquid biopsy or breath diagnosis. On the contrary, MIR …

The function of cells in their native habitat often cannot be reliably predicted from genomic
data or from physiology studies of isolates. Traditional experimental approaches to study the …

Mid-infrared (IR) spectroscopic imaging using inherent vibrational contrast has been broadly
used as a powerful analytical tool for sample identification and characterization. However …
