摘要： A method of forming a halide perovskite nanocrystal array having a plurality of halide perovskite nanocrystals arranged in a pattern can include coating an array of pens with a first ink comprising at least one first perovskite precursor having the formula AX and at least one second perovskite precursor having the formula BX'2 dissolved in a solvent. A is a cation, B is a metal, and X and X' are each a halogen. The method further includes contacting a substrate with the coated pen array to thereby deposit the first ink indias a pattern of printed indicia on the substrate. The printed indicia form nanoreactors on the substrate and a halide perovskite nanocrystal nucleates and grows within each nanoreactor to form the halide perovskite nanocrystal array.

摘要： The invention provides a sensor array with different nanodisk sensors that may be fabricated by direct site-specific dip-pen nanopatterning (DPN) using precursor inks. The good flow characteristics and strong affinity of the sols to measurement electrodes enable intimate ohmic contact. The measurable, reproducible and proportionate changes in the resistance of the sensors when exposed to trace quantities of oxidative and reducing gases constitute the basis for nanodisk gas sensors. The nanodisk sensors show rapid response and ultra-fast recovery for the detection of nitrogen dioxide and acetic acid vapor. Based on the principles of pattern recognition of the olfactory system, an electronic nose that can "smell" different gaseous species is provided with the multiple nanodisk sensor array. These nanodisk sensors have gas recognition ability, instant response and rapid recovery, compact size and integration with the established microelectronics platform and are wellsuited for the on-site and real-time detection of gases.
