Abstract: An atomizer includes: a liquid storage cavity for storing a liquid aerosol-generating material; and an atomization core arranged in the liquid storage cavity, the atomization core including: an outer tube arranged in the liquid storage cavity, at least one first liquid inlet hole in liquid communication with the liquid storage cavity being provided on the outer tube, a liquid storage member arranged in the outer tube so as to guide liquid, a center channel being provided in the liquid storage member, and an atomization assembly arranged in the center channel, the atomization assembly absorbing an aerosol-generating material transported by the liquid storage member and heating and atomizing the aerosol-generating material. Air path communication is formed between the liquid storage cavity and an outside so as to maintain the atomization assembly in an adequate state for absorbing the aerosol-generating material.

Abstract: An atomizing core for heating an aerosol-forming medium to form an aerosol includes: a fluid inlet for the aerosol-forming medium to enter the atomizing core; and an atomization assembly for heating and atomizing the aerosol-forming medium, the atomization assembly including a heating element and a mounting member for conducting the aerosol-forming medium; and a conductive assembly including a first conductive member and a second conductive member, the first conductive member being in fluid communication with the mounting member, and conducting to the mounting member the aerosol-forming medium entering from the fluid inlet, the second conductive member being in fluid communication with the mounting member, and a limiting portion being provided between the second conductive member and the first conductive member.

Abstract: Disclosed herein include a photoactivatable vibrational probe, when photoactivated, capable of forming a Raman probe for detection by Raman scattering. In some embodiments, the photoactivatable vibrational probe has a structure of Formula I. Disclosed herein also includes methods of using the photoactivatable vibrational probe for live-cell multiplexed imaging and tracking.
