A two-photon probe for real-time monitoring of intracellular free zinc ions is provided. The two-photon probe is represented by Formula 1:
wherein R is H or OCH
3
. The two-photon probe has high selectivity for Zn
2+
and enables very effective and long-term monitoring of intracellular free Zn
2+
present in the deep tissue. Further provided are a method for preparing the two-photon probe and a method for real-time monitoring of intracellular free zinc ions using the two-photon probe.

The present invention relates to a packaging article comprising: i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres; ii) at least one anhydrous dye composition containing at least one direct dye; and iii) optionally at least one anhydrous oxidizing agent; it being understood that the dye composition ii) and the anhydrous oxidizing agent iii), when it is present, are in one of the cavities defined by the envelope i). Another subject of the invention is the use of the said article for dyeing keratin fibres and a process for dyeing keratin fibres using the said article. The use of the packaging article makes it possible to obtain dye compositions whose consistency is pleasant on use, which are easy to apply and which make it possible to obtain powerful colouring of the hair.

The present invention relates to a process for dyeing and relaxing curls of keratin fibres, such as the hair, which comprises the application to the fibres of one or more acidic compositions comprising reducing agents and of one or more compositions comprising hair-dyeing agents, and a step of heat treatment of the fibres by means of a heating tool. A subject of the invention is also the use of the composition(s) comprising reducing agents and of the composition(s) comprising hair-dyeing agents in a process for dyeing and relaxing curls of keratin fibres. Finally, a subject of the invention is a multi-compartment device or “kit” suitable for carrying out such a process.
