Gold nanotip array for ultrasensitive electrochemical sensing and spectroscopic monitoring. Small, 9(13), 2260-2265. | Series/Report no.: | Small | Abstract: | A gold nanotip array platform with a combination of ultrasensitive electrochemical sensing and spectroscopic monitoring capability is reported. Adenosine triphosphate is detected down to 1 pM according to the impedance changes in response to aptamer-specific binding. Furthermore, the local molecular information can be monitored at the individual plasmonic nanotips, and hence provide the capability for a better understanding of complex biological processes. | URI: | https://hdl.handle.net/10356/102369 http://hdl.handle.net/10220/19017 |
