“体内医生”治疗癌症 纳米机器人或成明星产业

2014-01-07 佚名 生物谷

据路透社报道,韩国未来创造科学部日前宣布,韩国全南大学细菌机器人研究所已研发出世界上首个可治疗癌症的“体内医生”——纳米机器人(nanorobot),可对大肠癌、乳腺癌、胃癌和肝癌等高发性癌症进行诊断和治疗。据悉,该机器人由生物体细菌和药物的微型结构两部分构成,目前已经在动物身上取得成功实验。该机器人在找到癌症发病处后,其微型结构就会破裂,在病原体表面撒出抗癌剂。另据报道,德国科学家3日也宣称,其



据路透社报道,韩国未来创造科学部日前宣布,韩国全南大学细菌机器人研究所已研发出世界上首个可治疗癌症的“体内医生”——纳米机器人(nanorobot),可对大肠癌、乳腺癌、胃癌和肝癌等高发性癌症进行诊断和治疗。

据悉,该机器人由生物体细菌和药物的微型结构两部分构成,目前已经在动物身上取得成功实验。该机器人在找到癌症发病处后,其微型结构就会破裂,在病原体表面撒出抗癌剂。

另据报道,德国科学家3日也宣称,其最新发明的纳米机器人可以帮助受孕困难的夫妻解决生育难题,业内科研人员表示,这项技术是当前新型医院最为安全的治疗方式。

将广泛应用于医疗领域

纳米机器人属于分子仿生学范畴,它根据分子水平的生物学原理为设计原型,设计制造可对纳米空间进行操作的“功能分子器件”。医生利用纳米机器人可以让其直接围剿人体癌细胞,让化疗指向特定的治疗目标,从而避免在医学治疗过程中对人体其他内脏和细胞受到伤害。

据韩联社报道,韩国未来创造科学部研发的这款纳米细菌机器人直径为3微米,由大幅生物体细菌和药物的微型结构两部分组成,可利用遗传基因杀死癌细胞。机器人可避开抗癌剂等微型结构,准确找到引发癌症的病源。

该研究小组表示,实验已在老鼠身上取得成功,且实验结果表明,无论是癌症诊断的准确性还是治疗的针对性都是世界上最先进的。韩国未来创造科学部表示,若该机器人未来投入使用,将有可能发现早期癌症病原体然后注射抗癌剂。细菌机器人的成功开发在癌症诊断和治疗史上具有划时代的意义。

纳米机器人是纳米生物学中最具诱惑力的内容,相关资料显示:第一代纳米机器人是生物系统和机械系统的有机结合体,这种纳米机器人可注入人体血管内,进行健康检查和疾病治疗。还可以用来进行人体器官的修复工作、作整容手术、从基因中除去有害的DNA,或把正常的DNA安装在基因中,使机体正常运行;第二代纳米机器人是直接从原子或分子装配成具有特定功能的纳米尺度的分子装置;第三代纳米机器人将包含有纳米计算机,是一种可以进行人机对话的装置。

未来或成明星产业

业内人士预计,2014年,全球纳米技术产业市场规模将达2.6万亿美元,相当于IT和通信两大行业的总和。未来20-30年,纳米技术有望广泛应用于信息、能源、环保、生物医学、制造、国防等领域,促进传统产业改造和升级,并形成基于纳米技术的一系列新兴产业。

此前,专注于包括纳米技术在内新兴科技的投研一体组织LuxResearch特地设立了“LuxNanoTech指数”,美国PowerSharesLux纳米技术组合交易所交易基金(ETF)则专门跟踪此指数。设立初期,该ETF初始成分股中包括通用汽车、通用电气、IBM以及惠普等大型蓝筹股,但经历了自2007年次贷危机洗礼后,该指数将上述大盘成分股逐步剔除出了核心成分股的行列,替换进入的都是市值在2-10亿美元之间的中小市值纳米技术相关公司。LuxNanoTech指数2013年以来累计上涨21%至653.61点。目前,PowerSharesLux纳米技术组合ETF的持股包括Nanosphere(NSPH)和NanometricsIncorporated(NANO)等。

癌症干细胞标志蛋白被发现

  治疗癌症如果不把癌症干细胞彻底清除,癌症很容易复发和转移。日本京都大学的研究人员说,他们找到了癌症干细胞含有的一种标志蛋白,有望对癌细胞做到“斩草除根”。   京都大学消化内科教授千叶勉领导的研究小组在研究中注意到消化道中的一种蛋白质Dclk1,他们分析了罹患大肠癌的实验鼠,发现含这种蛋白质的细胞会在较长一段时间内持续产生癌细胞。他们通过基因操作成功地有选择地清除了含Dclk1蛋白质的细胞,
