WET UCIO is an inexpensive carbon-based powder suspension, reportedly as effective as commercially available formulations for latent fingermark detection on the sticky side of adhesive tapes. However, the surfactant solution used in WET UCIO is not readily accessible outside Europe, limiting its use in Seychelles or other non-European jurisdictions. In this study, the UCIO formulation was modified based on a 'frugal forensic' approach, by replacing the surfactant solution with an in-house sodium dodecyl sulfate solution prepared in 5 % aqueous ethanol. A comparative assessment against Wetwop™ using eight different pressure-sensitive adhesive tapes found that the modified formulation was at least as effective as commercial powder suspension. Modifying this technique under the frugal forensic framework has enhanced its accessibility to other jurisdictions and is recommended for validation in Seychelles.
WET UCIO 是一种廉价的基于碳的粉末悬浮液，据称在粘性胶带上检测潜在指纹方面与市售制剂同样有效。然而，WET UCIO 中使用的表面活性剂溶液在欧洲以外地区不易获得，限制了其在塞舌尔或其他非欧洲司法管辖区的使用。在这项研究中，根据“节俭取证”方法对 UCIO 制剂进行了修改，即用在 5%乙醇水溶液中制备的内部十二烷基硫酸钠溶液替代表面活性剂溶液。使用八种不同的压敏胶带对 Wetwop™进行的对比评估发现，改性制剂至少与商业粉末悬浮液同样有效。在节俭取证框架下对该技术进行修改，增加了其在其他司法管辖区的可及性，并建议在塞舌尔进行验证。
