BACKGROUND The autofluorescence background of biological samples impedes the detection of single molecules when imaging. The most common method of reducing the background is to use evanescent field excitation, which is incompatible with imaging beyond the surface of biological samples. An alternative would be to use probes that can be excited in the near infra-red region of the spectrum, where ...

Various infra-red and planar chiral metamaterials were fabricated using the modified Nanospherical-Lens Lithography. By replacing the light source with a hand-held ultraviolet lamp, its asymmetric light emission pattern produces the elliptical-shaped photoresist holes after passing through the spheres. The long axis of the ellipse is parallel to the lamp direction. The fabricated ellipse arrays...

Plasmonic sensors exploiting the localized surface plasmon resonance (LSPR) of noble metal nanoparticles are common in the visual spectrum. However, bio-sensors near the infra-red (NIR) windows (600–900 nm and 1000–1400 nm) are of interest, as in these regions the absorption coefficients of water, melanin deoxyglobin, and hemoglobin are all low. The first part of this paper reviews the work tha...

We show that in a special class of theories the commonly assumed universal form of the soft supersymmetry–breaking terms is approached in the infra–red limit. The resulting universal scalar mass and trilinear coupling are predicted in terms of the gaugino mass.

Elasto fibroma dorsi is a rare tumour of the shoulder girdle that usually arises at the infra scapular area. We present a 57-year-old male with a soft tissue swelling on his right infra scapular area of 6 months duration. It was a painless lesion which caused him discomfort while sleeping. Preoperative imaging revealed bilateral tumours but the left tumour was impalpable. The surgery itself was...
