技術說明

本技術先以溶膠凝膠法合成二氧化矽奈米微球，再以Langmuir-Blodgett沉積技術將奈米微球排列成單層陣列。藉由光子晶體和分子印記技術的結合，製備出一種能辨識L-色胺酸的反蛋白石水凝膠感測器。由於當具有特定分子印記的反蛋白石水凝膠與目標分子相匹配時，會引起水凝膠的溶漲或收縮，而導致Bragg繞射峰波長的改變。因此，本技術亦提供一種既具創新性又具實用性的色度分析技術來檢測L-色胺酸的微量濃度變化。此外，該感測器亦對目標分子L-Trp具有優異的專一辨識性，且可由其反射峰的位移及色度座標位置的改變來預測其濃度。本技術亦探討不同孔洞大小的反蛋白石水凝膠對不同濃度L-Trp溶液的刺激響應效應。 In this technology, silicon dioxide nanometer microspheres were synthesized by sol gel, and then the nanospheres were self-assembled into a mono layer array by Langmuir-Blodgett deposition technology. An anti-opal hydrogel sensor capable of identifying L-Trp is manufactured by combining photonic crystals with molecular imprinting techniques. The hydrogel will be swollen or shrunk as the target molecule matches the specific molecular imprint in an anti-opal hydrogel, which also causing a change in the wavelength of Bragg diffraction peak. Therefore, this technology also provides an innovative and practical chromatic analysis technique to detect the trace concentration of L-Trp. In addition, the sensor also has great exclusive-identification of the target molecule L-Trp, and its concentration can be predicted from the displacement of its reflective peak and the change of the color coordinate positions. The stimulating response for different concentrations of L-Trp solution to the inverse opal hydrogels with different pore sizes are also be investigated in this technology.
