隕石剩余磁化的磁場(chǎng)成像和光學(xué)成像

地質(zhì)樣本中的剩余磁化強(qiáng)度記錄了過去行星磁場(chǎng)的強(qiáng)度和方向。傳統(tǒng)上，這種磁化是通過測(cè)量尺寸在毫米到厘米的樣品凈磁矩進(jìn)行分析。然而地質(zhì)樣品通常在亞毫米尺寸上具有結(jié)構(gòu)和物質(zhì)的不均勻性，只有小部分鐵磁顆粒具有剩余磁化強(qiáng)度，因此需要高空間分辨率、高磁矩靈敏度的成像技術(shù)。

寬場(chǎng)NV顯微鏡通過減少金剛石與樣品之間的距離, 能夠?qū)崿F(xiàn)磁矩靈敏度10-16 A·m2的探測(cè)，能夠應(yīng)用于地質(zhì)、磁隕石的探測(cè)分析中。

肺癌組織熒光成像和磁場(chǎng)成像

傳統(tǒng)磁共振成像受限于低靈敏度和低空間分辨率，很難應(yīng)用于組織水平微米分辨率的成像。寬場(chǎng)NV顯微鏡結(jié)合量子精密測(cè)量與免疫磁標(biāo)記技術(shù)，能夠?qū)崿F(xiàn)高分辨率的腫瘤組織磁成像，可用于肺癌等檢測(cè)。

寬場(chǎng)NV顯微鏡在生物組織成像上具絕對(duì)磁定量、避免背景信號(hào)的干擾、磁信號(hào)的高穩(wěn)定性、兼具磁和光多模態(tài)成像等優(yōu)勢(shì)。
