Medical and dental professionals should wear gloves when examining all patients if contact with mucous membranes or other wet surfaces may occur. 医生和牙医在检查所有患者时,如需接触粘膜或其他湿面,一定要戴手套。
Contact with silane can cause irritation of the eyes. Inhalation may result in headache, nausea and irritation of the mucous membranes and respiratory tract. 接触硅烷会导致眼睛的刺激。吸入会导致头痛、恶心、黏膜和呼吸道的刺激。
Water contact angle measurement of the control and the modified PLLA membranes indicated that the hydrophilicity of the membrane was improved obviously after the grafting modification. 接触角测试结果表明改性后PLLA膜表面的亲水性明显提高。
Contact angle measurement indicates modified membranes are more hydrophobic and of higher benzene solubility than unmodified one. 接触角测量结果表明,改性膜的亲苯性和疏水性均增强。
Wa-ter contact angle of the membranes increased from 92 to 123 °, suggesting the hydrophobicity of the membranes was improved significantly. 改性后的膜疏水性显著提高,水接触角从92°提高到123°。
Contact angle measurement indicates that the membranes are more hydrophobic and of higher benzene ( solubility) than polydimethylsiloxane ( PDMS). 接触角测定结果表明2种膜比PDMS膜亲苯疏水性增强。
Hydrogels are widely used in biomaterials and pharmaceutical industry such as contact lenses, biosensor, biological membranes, artificial organs and drug delivery systems, due to their typical characteristics. 由于独特的性能,水凝胶在生物材料与药物工业上获得了广泛的应用,用于制备隐形眼镜、生物传感器、生物膜、人造器官、药物控释载体等。
