“…TPP resonance can be interrogated by reflection, transmission, absorption spectroscopy, intensity interrogation, or phase measurement [20]. Due to its prominent characteristics, TPP has wide applications in sensing [21], lasing [22,23], perfect absorber [24], solar cell [25], optical filtering [26], and nonlinear optics [27]. In particular, TPP sensing has been demonstrated for detection of temperature [28], pressure [29], surface deformation [30], refractive index (R.I.) [31], organic vapor [32], greenhouse gases [33], liquids [34], fat concentration in milk [35], blood components [36], and theoretically predicted to be suitable for biosensing [37].…”
