The present disclosure relates to a device and method for removing metal gallium, and a laser lift-off system. The device includes a device body, and the device body includes a process chamber (), wherein fluid used for removing metal gallium left on the surfaces of multiple Micro Light Emitting Diode (Micro-LED) chips after laser lift-off is contained in the process chamber (); and a temperature of the fluid is greater than or equal to a melting point of metal gallium.

Device and method for removing metal gallium, and laser lift-off system

The present invention relates to the technical field of medicines, and relates to a polyethylene glycol conjugated drug, a preparation method therefor and the use thereof. In particular, the present invention relates to a polyethylene glycol conjugated drug as shown in formula I or a pharmaceutically acceptable salt thereof. The present invention also relates to a method for preparing the polyethylene glycol conjugated drug or the pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the polyethylene glycol conjugated drug or the pharmaceutically acceptable salt thereof, and the use thereof in the preparation of a drug.

Polyethylene glycol conjugate drug, and preparation method therefor and use thereof

Disclosed are an intermediate drug having synergistic anticancer activity and a polyethylene glycol-coupled synergistic anticancer drug, and a method preparing therefor and use thereof. The intermediate drug has the general structural formula of (I), and the polyethylene glycol-coupled synergistic anticancer drug has the general structural formula of (II). The drugs achieve the combined medication of various anticancer drugs and avoid the toxic reaction caused by the interaction among the drugs or by the pharmacokinetics of the drugs when taking various anticancer drugs, facilitate overcoming the multidrug resistance of cancers, have a synergistic effect, and can be used for preparing anticancer medicaments and for treating cancers.
