Abstract: A processor chip including a memory controller, application processor and a communication processor, where the memory controller is configured to define an area of memory as secure memory, and allow only an access request with a security attribute to access the secure memory. The application processor is configured to invoke a secure application in a trusted execution environment, and write an instruction request for a secure element into the secure memory using the secure application. The communication processor is configured to read the instruction request from the secure memory in the trusted execution environment, and send the instruction request to the secure element. The application processor and the communication processor need to be in the trusted execution environment when accessing the secure memory, and access the secure memory only using the secure application.

Abstract: Embodiments of the present application disclose a near field communication method and a mobile terminal. After receiving an AID selection command that is used for initiating an NFC service and that is sent by an NFC controller, the AP parses the AID selection command to obtain a target AID. Then, the AP searches the AID routing table to obtain a first destination address corresponding to the target AID. If an object corresponding to the first destination address is an SE, the AP establishes a first link between the AP and the SE. The AP sends, to the SE, all subsequently received service data that belongs to the same NFC service as the AID selection command, until the AP receives a new AID selection command.

Abstract: A composition comprising a macromer that can be in situ polymerized into a hydrogel wound dressing directly on a wound and one or more antimicrobial agents intended to achieve bacteriostasis and/or be bacteriocidal. The antimicrobial agent is released upon application and trapped in the hydrogel upon its formation and also released over a period of time into the wound.

Abstract: Multifunctional nanoparticles for imaging and therapeutic drug delivery made from amphiphilic block copolymers having a hydrophobic block and one or more hydrophilic blocks, and at least one internal and one terminal chelating agent units having a paramagnetic metal ion associated therewith.

Abstract: Vesicles for use in biosensors that have both high specificity and high sensitivity, where the vesicles include a receptor specific for the intended analyte and a signal generating component.

Abstract: Vesicles for delivery of active macromolecules, such as oligoaminoacids, oligonucleotides, microRNA, siRNA, dsRNA, single stranded oligonucleotides, DNA, peptide nucleic acids, peptides, proteins, and some synthetic organic drugs which are made from amphiphilic segmented copolymers where one segment contains the active macromolecule. In one preferred embodiment, the active macromolecule is contained in the hydrophilic C segment of an amphiphilic ABC segmented copolymer.

Abstract: A drug delivery vehicle having active agent loaded vesicles in a hydrogel matrix; desirably either or both of the vesicles and matrix are made of at least one stimulus responsive polymer so that active agent is released in response to contact with a stimulus.
