New near-infrared dyes light up deep tissue imaging filetype pdf
White light microscopy is primarily used for routine analysis (monitoring cell number and morphology after seeding of scaffolds) and for imaging stained tissue slices (histology ; various stains such as H&E, Von Kossa, trichrome, alcian blue and others are available [39,50,66–71]).

The new agents were molecularly altered to carry fluorescent dyes that glow under lights with specific wavelengths – either in the green (CLR1501) or near-infrared (CLR1502) range. Viewed under appropriate conditions, the dyes make tumour cells “light up” so that they can be readily distinguished from neighbouring normal brain tissue.
Near-infrared (NIR) dyes are used extensively for biomedical imaging applications, owing to enhanced tissue penetration of light in the NIR window.[1, 2] A wide range of contrast media has been explored for NIR fluorescence and photoacoustic in vivo imaging.[3-21] Cyanines are amongst the most commonly-used NIR dyes.[22-24] They can form end-to-end “J-aggregates” with red shifted
Prof Zhang said the use of near-infrared light, which is invisible to the human eye, is unique as most imaging techniques use ultraviolet light or visible light. “Near-infrared light can penetrate 3 to 4 cm beyond the skin to deep tissue, much deeper than visible light.

Near-infrared (NIR) fluorescent probes have been considered as powerful tools for exploring bioactive species and biological processes in living systems by virtue of the substantial merits of the NIR window (such as minimal photo-toxicity, deep tissue penetration, and low background interference).
The new agents were molecularly altered to carry fluorescent dyes that glow under lights with specific wavelengths, either in the green (CLR1501) or near-infrared (CLR1502) range. Viewed under appropriate conditions, the dyes make tumor cells “light up” so that they can be readily distinguished from neighboring normal brain tissue.
Thurber’s team uses a dye that responds to infrared light to tag a molecule commonly found on tumor cells, in the blood vessels that feed tumors and in inflamed tissue. By providing specific information on the types of molecules on the surface of the tumor cells, physicians can better distinguish a malignant cancer from a benign tumor.
A spectral window in the far-red to near-infrared (NIR) range (650–1100 nm) corresponds to low absorption and scattering of light by tissue and allows light to penetrate up to several centimeters into tissue.
Near-infrared light, or light with a wavelength between 650-900 nanometers, is ideal for bioimaging because it penetrates deep into tissues without damaging natural cells or causing them to fluoresce.

Abstract. C dots (CDs) have shown great potential in bioimaging and phototherapy. However, it is challenging to manipulate their fluorescent properties and therapeutic efficacy to satisfy the requirements for clinic applications.
Near-infrared fluorescence (NIRF) imaging has recently emerged as a useful tool for noninvasive cancer imaging . NIRF agents show very limited autofluorescence from intrinsic chromophores, but upon binding to biomolecules they display drastically increased fluorescence due to rigidization of the fluorophores [ 2 , 3 ].
It has been previously shown that light within the near infrared (NIR) window (650 – 900 nm) exhibited greatest tissue penetration capability. Consequently, tissue-penetrable NIR-sensitive dyes are often utilized as the photo-responsive agents to generate effects of hyperthermia [ 11 – 14 ], photoacoustics[ 15 , 16 ] or photoluminescence[ 17 ] within the whole tumor region.
Plus, the new dye has an additional advantage since it fluoresces under both near-infrared light and visible light. “Near-infrared is useful in biomedical research because it penetrates deep

Since light scattering and absorption in human tissue are the major obstacles in optical fluorescence imaging, NIR wavelength (700–900 nm) can efficiently minimize tissue autofluorescence, resulting in less background interference and enhanced signal-to-background ratio 29,30,31,32.
The dye was developed after it was learned that chlorotoxin, a protein found in scorpion venom adheres to chloride receptors on the surface of tumor cells.
Imaging in the near-infrared (NIR) window (700-900 nm), also known as the “therapeutic window” has tremendous potential by offering low absorbance and scattering in tissues while providing maximum depth of light penetration .

Newly Developed Dye Washington Red Could Advance
Near-infrared fluorescence (NIRF) imaging has recently emerged as a useful tool for noninvasive cancer imaging . NIRF agents show very limited autofluorescence from intrinsic chromophores, but upon binding to biomolecules they display drastically increased fluorescence due to rigidization of the fluorophores [ 2 , 3 ].

Prof Zhang said the use of near-infrared light, which is invisible to the human eye, is unique as most imaging techniques use ultraviolet light or visible light. “Near-infrared light can penetrate 3 to 4 cm beyond the skin to deep tissue, much deeper than visible light.
