中國傳統墨汁的藥效引起科學家的興趣。一項研究指出，墨汁具有抗癌功效，其機制與其所含納米顆粒有關。

據健康網站professorhealth 1月23日報導，人們都知道，在中國傳統文化中，黑黑的墨可用來表現極為優美的藝術，例如中國書法和水墨畫。

科學家也關注墨汁的藥用效果，並嘗試探討其藥理機制。

《美國化學會OMEGA刊》（ACS Omega）一篇報告說 .

墨汁對於癌症向淋巴結的擴散和轉移，具有非侵入性的治療作用，也就是說墨汁是一種不會給患者造成傷害的有效抗癌藥物。

癌細胞經常會從淋巴管向病灶外轉移。對此，西方醫學主要使用手術切除方法進行治療，但是副作用大，而且無法控制復發。

因此，近年來出現非侵入性光熱療法（PTT），來抗擊癌細胞轉移。該方法使用納米材料來殺死癌細胞，但是這些納米材料有毒、難以加工生產和價格昂貴。

科學家發現，中國墨汁具有類似光熱療法納米材料的作用，卻無毒且價格便宜，有用於治療癌症的潛力。中國墨汁的制備原理是煤煙、松煙與明膠等混合，也就是製成碳元素、水和膠的混合物。研究者選擇胡開文墨（Hu-Kaiwen ink），對此加以分析。胡開文墨汁創於清朝乾隆年間，距今已有近250年的生產歷史。

科學家發現，這種中國傳統工藝製作的黑色混合液體含有納米顆粒，其中碳原子形成薄層結構。胡開文墨汁在激光下加溫後，溫度可以升高至55攝氏度（131華氏度）。因此，這種墨汁經過光熱療法（PTT）所用的激光照射，能夠在實驗條件下殺死癌細胞，而且墨汁顆粒具有探測癌細胞的作用。科學家希望將墨汁用于開發抗癌新療法。

實際上，中國以墨汁為藥的歷史超過一千年。據宋朝開國皇帝指定修撰的藥典《開寶本草》記載，好墨可以入藥。按照中醫理論，墨的藥味「辛、平」，可歸入心、肝和腎三個臟器所屬的經絡，具有止血、消腫的功效，可用于孕婦产后血晕等疾患。＃

“New Application of Old Material: Chinese Traditional Ink for Photothermal Therapy of Metastatic Lymph Nodes”
ACS Omega

For hundreds of years, Chinese calligraphers have used a plant-based ink to create beautiful messages and art. Now, one group reports in ACS Omega that this ink could noninvasively and effectively treat cancer cells that spread, or metastasize, to lymph nodes.

As cancer cells leave a tumor, they frequently make their way to lymph nodes, which are part of the immune system. In this case, the main treatment option is surgery, but this can result in complications. Photothermal therapy (PTT) is an emerging noninvasive treatment option in which nanomaterials are injected and accumulate in cancer cells. A laser heats up the nanomaterials, and this heat kills the cells. Many of these nanomaterials are expensive, difficult-to-make and toxic. However, a traditional Chinese ink called Hu-Kaiwen ink (Hu-ink) has similar properties to the nanomaterials used in PTT. For example, they are the same color, and are both carbon-based and stable in water. So Wuli Yang and colleagues wanted to see if Hu-ink could be a good alternative material for PTT.

The researchers analyzed Hu-ink and found that it consists of nanoparticles and thin layers of carbon. When Hu-ink was heated with a laser, its temperature rose by 131 degrees Fahrenheit, much higher than current nanomaterials. Under PPT conditions, the Hu-ink killed cancer cells in a laboratory dish, but under normal conditions, the ink was non-toxic. This was also the scenario observed in mice with tumors. The researchers also noted that Hu-ink could act as a probe to locate tumors and metastases because it absorbs near-infrared light, which goes through skin.
