    • A skin treatment formulation, e.g. in the form of an ointment or gel or a skin dressing, comprises a photocatalytic agent, e.g. flavine mononucleotide, and an electron donor substance, e.g. ethylene diamine tetra acetic acid, conveniently in the form of an agar gel (10). On exposure to light in the presence of oxygen (e.g. from the ambient atmosphere) the photocatalytic agent acts to cause conversion of oxygen to hydrogen peroxide. If this reaction occurs on or in the vicinity of skin, the hydrogen peroxide so produced can have a localised antibacterial effect. By controlling exposure to light, so hydrogen peroxide can be generated in situ in the vicinity of skin in a way that has not hitherto been possible.
    • 皮肤处理制剂,例如 以软膏或凝胶或皮肤敷料的形式,包含光催化剂,例如, 黄烷单核苷酸和电子供体物质,例如, 乙二胺四乙酸,方便地以琼脂(10)的形式存在。 在氧气存在下(例如从环境气氛中)暴露于光时,光催化剂起氧气作用,导致氧气转化为过氧化氢。 如果该反应发生在皮肤上或皮肤附近,则如此产生的过氧化氢可具有局部抗菌作用。 通过控制暴露于光,因此过氧化氢可以以迄今为止尚未成形的方式在皮肤附近原地产生。

    • Apparatus for detecting a specific target odour comprises: a detector unit adapted to have removably associated therewith a holding unit for housing at least one insect in a predetermined position; means for exposing an insect in a holding unit associated with the detector unit to a sample of gas to be tested; and means for enabling monitoring of a response of the insect to the sample thereby to detect a response indicative of the target odour. In use of the apparatus, a holding unit housing at lest one insect that responds in a detectable manner to the target odour is associated with the detector unit. A sample of gas to be tested is supplied to the apparatus, for exposure to the insect or insects in the holding unit. The insect is monitored for a response indicative of the target odour, thus enabling determination as to whether or not the target odour is present in the sample. Because the holding unit is not part of the detector unit but is removably associated with therewith, the holding unit can be used to transport an insect or insects housed therein from a first, remote location, e.g. where insects are raised and conditioned, to a point of use at a second location where the detector unit is located. The detector unit may be a permanent or semi-permanent fixture at a point of use, or may be in the form of a portable unit. Also disclosed is a method of detecting a specific target odour.
    • 用于检测特定目标气味的装置包括:检测器单元,其适于具有可移除地与其相关联的保持单元,用于将至少一个昆虫容纳在预定位置,用于将与所述检测器单元相关联的保持单元中的昆虫暴露于气体样本 被测试和用于使得能够监测昆虫对样品的响应的装置,从而检测到指示目标气味的响应。 在使用该装置时,将至少一个以可检测的方式响应于目标气味的昆虫的保持单元与检测器单元相关联。 将待测试的气体样品供应给设备,用于暴露在保持单元中的昆虫或昆虫。 监测昆虫的指示目标气味的响应,从而能够确定样品中目标气味是否存在。 由于保持单元不是检测器单元的一部分,而是与其可拆卸地相关联,所以保持单元可以用于从第一远程位置(例如,第二位置)运送容纳在其中的昆虫或昆虫。 其中昆虫被升起和调节,到达检测器单元所在的第二位置处的使用点。 检测器单元可以是在使用点处的永久或半永久性固定装置,或者可以是便携式装置的形式。 还公开了检测特定目标气味的方法。
