Abstract: A near infrared dye comprising a counterion and a structure of Formula I
wherein the at least one of R1 and R2are 1-(thiophen-2-yl)piperidine, 1-(thieno[3,2-b]thiophen-2-yl)piperidine or 1-([2,2′-bithiophen]-5-yl)piperidine, and X, R, R3-R4, R19, R20 and R22-R29 are disclosed herein. Materials and compositions comprising the NIR dye can absorb light in the NIR I & II regions and then the energy can be released in the form of light (fluorescence) or heat (non-radiative). The dyes can also convert the absorbed light to heat and ultrasound waves via the photoacoustic effect. The photoacoustic effect can be used in photoacoustic tomography to image biological materials or processes. Methods for synthesizing the NIR dyes and materials comprising the same are also disclosed.-

Abstract: The invention relates to a method for counting cells, such as bacteria and/or somatic cells in liquid samples, such as in dairy products, preferably raw milk. Disclosed is a method comprising a combination of steps that apply dimeric nucleic acid dyes that normally do not penetrate cells (=cell-impermeant dyes), which are rendered cell-permeant by using the right combination of pH, buffer and temperature.
