一位独立研究者基于科学论文的启发,在家庭实验室中尝试用酒石酸盐溶液浸泡鸡胸肉,成功实现了肉类的部分透明化1。这种酒石酸盐是玉米脆饼中的黄色食用色素,分子式为 C16H9N4Na3O9S21。通过两次实验,研究者采用约 0.19M 浓度的溶液在室温下浸泡鸡胸肉 6 到 12 小时,使 2 毫米厚的样品呈现出部分透明性,能够清晰看到下方的网格线1。
该技术的原理在于改变水与蛋白质和脂肪的折射率匹配程度1。水的折射率约为 1.33,而蛋白质和脂肪结构的折射率约为 1.451。通过酒石酸盐溶液调节光学性质,使两者折射率接近,从而减少光散射,实现透明效果1。这一方法源自 2024 年 9 月 6 日发表在《科学》杂志上的论文,由 Ou Z 等研究者撰写,标题为《在活体动物中用吸收分子实现光学透明》1。研究者所使用的浓度相比原论文的 0.62M 更低1,目标是使独立科学家能够在家中进行荧光成像和组织结构观察1。
An independent researcher has successfully replicated an experiment to render chicken breast partially transparent by immersing it in a tartrate salt solution derived from Dorito seasoning.1 The author conducted two trials using approximately 0.19M concentration of the tartrate salt compound—a lower concentration than the 0.62M used in the original scientific paper—soaking 2mm-thick chicken samples at room temperature for either 6 or 12 hours.1 The treatment produced samples with sufficient optical clarity to reveal grid lines visible through the tissue, demonstrating that the technique can be performed outside a professional laboratory setting.1
The experiment is based on the principle of refractive index matching, whereby the tartrate solution alters the refractive properties of the surrounding medium to align more closely with those of the chicken's protein and fat structures.1 Water naturally has a refractive index of approximately 1.33, while protein and fat molecules in tissue have a refractive index of around 1.45; the tartrate solution bridges this difference.1 The researcher's work builds on a peer-reviewed study published in Science on September 6, 2024, by Ou Z and colleagues titled "Achieving optical transparency in live animals with absorbing molecules."1 By making this technique accessible to independent scientists working in home laboratory settings, the approach enables fluorescence imaging and direct observation of tissue structure without requiring institutional resources.1
