Detection and photothermal inactivation of Gram-positive and Gram-negative bloodstream bacteria using photonic crystal biosensor and plasmonic core–shell

“…The first step to express light-to-heat conversion process is calculated employing absorption cross-sections ( C abs ), extinction coefficients ( C ext ), and light absorption capacity ( A abs ), 70 using well known Mie theory is given by eqn (7) to (9), 71,72 and C abs = C ext − C sca .In which the light absorption capacity is , for volume of nanosphere ( V p = 4/3π r j 3 ), volume of nanorod ( V p = π r j 2 l here l is length of rod), and volume of plate ( V p = π r j 2 t t is thickness of plate core–shell). Where,For whichandHere, r c and r s are inner and outer radius of core–shell respectively, X j and Y j are determinants, η j is spherical Bessl function, ξ j is spherical Nuemann function, ψ j and Φ j are Riccati–Bessel function, and is wave number for ε j is permittivity in which j = c,s,m.…”

A review on hybridization of plasmonic and photonic crystal biosensors for effective cancer cell diagnosis

“…Employing eqn (5) the performance analysis of plasmonic biosensor in angle interrogation modalities are defined by 100 full width at half maximum , sensitivity for Δ n anlayte is changed in the refractive index of analyte, figure of merit , detection accuracy , limit of detection , and resolution ( R = LoD × S ). In addition, for wavelength interrogation, the performance analysis is discussed in ref.…”

The Quantum Features of Correlated Photons with the Effect of Phase Fluctuation

“…Moreover, the existence of the entanglement can be studied through certain experimental and mathematical criteria [14][15][16]. For example, the famous positivepartial-transpose (PPT) is the experimental criterion [17].…”
