New method maps frozen organic particles precisely

New imaging method precisely maps organic particles, revealing elements like calcium, phosphorus, and silicon with unprecedented clarity. Tohoku University researchers developed a cryo-EELS/EF-TEM technique that overcomes limitations of existing methods, allowing detailed analysis of frozen organic nanomaterials without sample damage or image blur. This advancement enables the study of delicate biological and soft organic samples, overcoming challenges posed by ice and drift that previously hindered elemental mapping.
