“…In the biochemical analysis and detection system, the multifunctional integrated repeatable operating platform is always the goal scholars are keen to pursue [ 1 , 2 ]. For example, several key steps in single cell analysis (such as cell capture [ 3 ], arrangement [ 4 ], separation [ 5 ], and other operations) are integrated on one platform to realize free switching of multiple functions. There are various methods of cell manipulation based on microfluidics, mainly divided into passive techniques [ 6 , 7 , 8 ] and active techniques [ 9 , 10 , 11 ].…”

Multifunctional, integrated, and reusable operating platforms are highly sought after in biochemical analysis and detection systems. In this study, we demonstrated a novel detachable, reusable acoustic tweezer manipulation platform that is flexible and versatile. The free interchangeability of different detachable microchannel devices on the acoustic tweezer platform was achieved by adding a waveguide layer (glass) and a coupling layer (polydimethylsiloxane (PDMS) polymer film). We designed and demonstrated the detachable multifunctional acoustic tweezer platform with three cell manipulation capabilities. In Demo I, the detachable acoustic tweezer platform is demonstrated to have the capability for parallel processing and enrichment of the sample. In Demo II, the detachable acoustic tweezer platform with capability for precise cell alignment is demonstrated. In Demo III, it was demonstrated that the detachable acoustic tweezer platform has the capability for the separation and purification of cells. Through experiments, our acoustic tweezer platform has good acoustic retention ability, reusability, and stability. More capabilities can be expanded in the future. It provides a simple, economical, and multifunctional reusable operating platform solution for biochemical analysis and detection systems.

“…Among them, spiral zone plate (SZP ) plays a prominent part in generating optical vortices even when structured as photon sieves [14,15]. Additionally, optical vortices manifest the presence of angular momentum so they provide wide potential applications in magnetic fields generation [16][17][18][19][20][21], optical trapping [22,23], optical communications [24,25], quantum memory [26], sensing tools [27,28], global weather patterns [29], optical microscopy [30,31], and so on.…”

By taking advantage of spiral petal-like zone plates, we have recently demonstrated that a spiral element's geometric shape impacts its charge. Keeping it in mind, we aim to control the topological charge of a vortex using phase modification of a spiral zone plate without transforming its geometrical shape. This is achieved by apodizing a spiral zone plate having p spiral zones with a radial grating with spatial frequency m. Having implemented some gratings with different m, we realized that an optical vortex is produced whose topological charge and its handedness depend on p and m. Consequently, a constant phase replaces on-axis screw dislocation under the situation that p takes odd multiples of m. Studies are carried out for large and small pairs of (p, m) and various gaps between the couple.
